ok thx

anonymous · Answer

First apply product rule to (1+4x)^5 and (3+x-x^2)^8

anonymous · Answer

Chain rule is applied when finding the derivatives of those two polynomials.  What you do is take the derivative of the thing overall (the (1+4x)^5 derives to 5*(1+4x)^4) and multiply it by the inside of it (   the 1+4x derives to 4)  So the derivative of (1+4x)^5 is 5*4*(1+4x)^4.

Using what I showed you for that one, can you figure out how to derive (3+x-x^2)^8?
