if it was really X10 and not *10 then itd be 01-876-192-000 (theres no period separating the (y^2-10^2) and the x10 like there is for the other parts of the number) otherwise it would be 01-876-8000

...This is just basic algebra, stuff you take in middle school. What`s the big deal? I would definitely not trust this company if they`re willing to hire people who can only solve this level of difficulty.

i like how everyone says its easy and doesnt state the answer, wheras people who actually know what they are talking about point out that the last part of the equation doesnt make sense because it can be interpreted multiple ways

although it should be either 10x or *10 to make it more proper

Of course... how did I know that somehow this would spark argument over maath jargon, with one side being the side that can think and do math and the other side being one that just acts like they know what they`re doing.

Engineering.... stressful as drat... take it from me as a biomedical engineer.... uuuuugh... i dont want to study for thermodynamics... any one want to take the exam for me? please :D

seriously they should have at least givn an rational indefinite integral composed of functions that can`t be integrated by means of simple substitution.

p.s. because when people call for work in the north america... they are calling from united kingdom/europe/someplace where you dial 01 first

* walk into drug store* *oh look there is a poster for engineers, sweet i am one i want a job* *fly home to london* *good thing i took a number off that ad for engineers!* *figure out problem and dial number*

So many people are saying "Its so easy", but I`ve seen one person get it right, then correct themselves and make it wrong.

Its a Swiss phone number. The periods are intentional. They are to break up the phone number, because any number put in front of a bracketed equation becomes part of the equation and the author of the problem didnt want it to become a single figure.

The answer therefore is 01.876.8000 (Local Number)

I`d be willing to take your test for you, but I must bring up 2 issues :

A. I know very little about thermodynamics. B. If I could pass for you (in terms of looks), then you have some serious problems.

Loving the number of people here who really don`t get the point of what they are looking at!! That is not a job advertisement posted by a company which thought that was actually a difficult problem... that at least is obvious!

Who know`s if its even a real ad? Could just be a joke..

I did it all wrong. I went back and looked at the problem again and instead of y to the second power I did x. Oops. I tried it the right way and got 876-8000. Does anyone know the right answer?

i think they shohuld have used integrals instead, that may have gone better. at least integrals can separate the 13 year old asians from the 16 year old asians.

Ya not that hard they already did most the work for you be telling you what X and Y represent from there it`s all simple Multiplication and subtraction btw 876-8000 is the number... if only i had an area code i could get a job =P

raikun, that`s just what i call it. i know it`s really the "substitution rule" for integrals, but i liek calling the reverse chain rule, cause that`s wat u do :P

aha! This is a trick question! Average humans will either say it`s a joke, or figure that it`s just 7th grade work and do it themselves. But one who is truly wise in the ways of the computer and the internet knows that there is a website somewhere that could solve this problem for you.

- Have a Computer Engineering job you need to fill? Need to weed out the flunkies from the geniuses? Use this solution.
i think.

haha.

faaaaaaaaaaaail.

phail.

fayel.

oh dear.

PS i think the answer is 019 1125.

1) It`s just straight substitution, and it`s really, really easy.

2) The fact that you are all getting different (and wrong) answers means that it`s working at flunking out all the idiots.

3) You are all idiots.

4) Except for the 1 person who has posted before me with the correct answer.

brilliant.

I can do this and I`m only in algebra 2!

(01.)876 - 8000

01-546-4760

It doesn`t filter out the good engineers from the bad ones, but it definitely stops all the math-impaired potential spammers.

(theres no period separating the (y^2-10^2) and the x10 like there is for the other parts of the number)

otherwise it would be 01-876-8000

i wouldn`t even try, i fail at maths, completly.

and is that a minus in the middle or a .? this equation is fail

3*

...Clever idea though.

but to be honest.. the bulk of people dont know how to do simple bedmas. the whole double minus or double plus stuff doesnt click. i blame the schools

AM I A PROGRAMER

I did that in less than a minute in my head. whoop-dee-friggin-do.

although it should be either 10x or *10 to make it more proper

Is this not an American phone number, British maybe?

01.876.8000.240

Saw the x as a multiplication symbol... Sorry, its American. Easy problem.

"I wouldn`t join a company where that is the only requirement"

It`s a joke.

"That`s really easy"

It`s a joke.

"That last bit can be interpreted in several ways"

It`s a joke.

PS: The answer is 01-876-8000. Yes it can be interpreted in several ways, but the other options make no sense.

01-876-192000 is too long.

01-681-92000 swaps between multiplier symbols mid equation.

700-8000 Inserts a pointless start 0 as a multiplier.

(And adding a 240 at the end breaks the pattern of dividers).

or

01 876 800 192000 hmm

900-24= 876

900-100=800

1(876) x (800) =

710800

710800 x 10 = 7108000

710-8000

And I don`t know the first thing about computer programming.

not hard to work out at all, 01.876.8000 not a complicated problem.

Wow is your head the size of the earth? I mean with your ego?

I like it.

I`d be willing to take your test for you, but I must bring up 2 issues :

A. I know very little about thermodynamics.

B. If I could pass for you (in terms of looks), then you have some serious problems.

not too tough if you knwo what all the symbols mean :)

y = 30

01.(y^2-x).(y^2-10^2)x10

01.(30^2-24).(30^2-10^2)x10

01.(900-24).(900-100)x10

01.(876).(800)x10

01.876.8000

ja?

really creative. i like it

lol

Calculus FTW!

Who know`s if its even a real ad? Could just be a joke..

Cute idea though.

1(900-24) - (900-100)X10

(876) - (8000)

876-8000?

i think they shohuld have used integrals instead, that may have gone better. at least integrals can separate the 13 year old asians from the 16 year old asians.

maybe he should have used a reverse chain rule within that integral as well. perhaps add a few natural logs just to piss people off.

01.876.8000

or well, that`s what i like to do D:

01.876.8000

nothing burns my eyes more than seeing "math" where "maths" should be written.
