Good evening Cheryl! These integrations are of the form k * f’(x) * f(x) where f’(x) is the derivative of f(x). This integrates to some multiple of a raised power of f(x).
I will look at this later.

Always solve (be it differentiating/ integrating) from outside the brackets to within the brackets. For differentiation, you multiply the value obtained to the final result; for integration, use division.

Good evening Cheryl! Here are my workings for the second one. As long as the integral is in the form f’(x) multiplied by [f(x)]^n, the whole thing integrates to [f(x)]^(n + 1) divided by (n + 1).
