x^2(5 x^3 + 9)^3 dx

**Reiny**, Wednesday, April 9, 2014 at 10:47pmI observed that the derivative of the inside of the bracket sits out front as a multiple of that.

If that is the case, I just reverse by "thinking"

if dy/dx = x^2(5x^3 + 9)^3

y = (x^2/(15x^2)) (5x^3 +9)^4 * (1/4)+ c

= (1/60) (5x^3 + 9)^4 + c
