Homework Help: Calculus STUCK

Posted by -Untamed- on Tuesday, October 4, 2011 at 10:03pm.

Dont know if the radicals will show up..

23(243-2)-2(5+72) Can be expanded and simplified to the form
p + q2 + r3. the value of p + q + r is_____

First I simplified the V243 and I got 9V3

2V3(9V3-2)-V2(5+7V2)
18V9-4V3-5V2-7V2
54-4V3-5V2-7V2
54-4V3-12V2

But this just doesnt work out, and i have no idea what ive done wrong.
