what's the first derivative for:
$x^2(x+1)^3$

$\left[ {x^2 (x + 1)^3 } \right]' = \left( {x^2 } \right)'(x + 1)^3 + x^2 \left[ {(x + 1)^3 } \right]' = 2x(x + 1)^3 + 3x^2 (x + 1)^2$

hi,u can xpand (x+1) whole cube in the form of(a+b)''' and multiply it with x".then u can normally integrate. the answer is x''''''/6+3x'''''/5+3x'''''/4+x'''/3 i guess........

Why are you integrating here...? The problem is to find the derivative...
