I have this problem:
The chain rule states F'(x)=f'(g(x))*g'(x). The chain rule with powers is (un)'=nun-1(u').
I've tried this problem a thousand different ways (a sure sign I'm doing it wrong) and cannot seem to get the answer. I peeked at the back of the book and found it the answer is g'(x)=4(1+4x)4(3+x-x2)7(17+9x-21x2).
I cannot figure out how and I've been pulling my hair out all weekend. Please help me!
g(x)=(1+4x)5(3+x-x2)8
and I must find the derivative.The chain rule states F'(x)=f'(g(x))*g'(x). The chain rule with powers is (un)'=nun-1(u').
