I need help with these two review calculus problems for my final exam.

What is the derivative of

a). (5x^2+9x-7)^5

b). Lne^x^3

For a. I got 50x+45(5x^5+9x-7)^4

For b. I got 3x^2

• Calculus -

wolfram alpha

When you see lis of results click on:
Wolfram Alpha:Computational Knowledge Engine

When page be open in rectangle type:

derivative (5x^2+9x-7)^5

and click option =

After few secons you will see result.

Then clic option Show steps

Then type :

derivative Ln(e^x^3)

and click option =

and show steps
