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

Can you verify please?

  • Calculus -

    In google type:
    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
