So I'm left with 9 - 9root2 (I think, 3 x -2root2 is -9root2 right?) Also value of 8^-2/3 (two thirds) (1/8)^2/3 ((1/8)^1/3)^2 = (1/2)^2 = 1/4 amirite? edit: hello i use paint easier to see Re: quick maths halp - aaaaaaasd - 09-19-2011 05:51 AM I looked at that image for a good 5 seconds and my mind immediately turned into cheese, thanks elfy now how will i operate with a lactose brain Re: quick maths halp - Faby - 09-19-2011 05:53 AM Jesus Christ, get that shit away from me. That's EXACTLY why I went to a philology section in high school.

Re: quick maths halp - Blobthe15 - 09-19-2011 07:14 AM jesus fucking christ what Re: quick maths halp - LOON_ATTIC - 09-19-2011 07:15 AM Elfy Wrote:but the 2sqrt2 is negative so wouldn't it equal -4 making it 5-3*sqrt2? Shit yeah you're right what the fuck am I doing Re: quick maths halp - .Manicrose. - 09-19-2011 09:28 AM I just fell off my chair. I find this thread fucking hilarious. Doesn't help that every time someone writes "13-3*sqrt(2)" or something I think for a second that it actually says "13-3*SQUIRT(2)" teehee hee HEE This thread brings light into my life. yes i am a little drunk right now in case you were wondering Re: quick maths halp - The Desert Fox - 09-19-2011 12:18 PM Faby Wrote:Jesus Christ, get that shit away from me.

SKWERT!!! Yeah, sorry, I am of no help. If the solution to that equation was actually for some good purpose, or useful in any way, I might look into it... but it isn't... so fuck it. Re: quick maths halp - aaaaaaasd - 09-20-2011 12:34 AM Why must maths be more useful than english damnit Re: quick maths halp - UnschoolShqiponjÃ« - 09-20-2011 02:14 AM Faby Wrote:Jesus Christ, get that shit away from me.
