I'll get back to math on monday, and check this out!

I totally messed this one up... and I thought I was doing better. (Doh) (Angry) (Crying)

Thank you so much! It totally sounds right.

... but the actual answer is a-b, right? - August 16th 2008, 06:08 AMvishalgarg
hi neoon

it is a simple case of x^3 - y^3

where x = a^1/3

n y = b^1/3

so ans will be a-b - August 19th 2008, 04:08 PMNeenoon
