Help differentiating.

Can anyone help me with this question? I can do it all the way, but at the very last step my textbook somehow gets rid of all the exponents on one side, anyone know why or how?

Here are the questions

39. (8x-1)^3(2x+1)^4

40. (3x+2)^5(4x-5)^2

This is how the textbook solved it

Re: Help differentiating.

They carefully pulled out the common factors and simplified.
