I need help with these two review calculus problems for my final exam.
What is the derivative of
a). (5x^2+9x7)^5
b). Lne^x^3
For a. I got 50x+45(5x^5+9x7)^4
For b. I got 3x^2
Can you verify please?

In google type:

When page be open in rectangle type:
derivative (5x^2+9x7)^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
