Power rule

## The Attempt at a Solution

a.) would you do the power rule for this? 2tanx

b.) this is a combination of the chain rule and the power rule?

-3sinx

^{2}*2x

c.) use the quotient rule

((5x+2)(2)-(2x-1)(5))/(5x+2)

^{2}

((10x+2)-(10x-5))/(5x+2)

^{2}

7/(5x+2)

^{2}

d.) use the chain rule and the product rule?
