Answer 5

In will be cancelled? and x becomes the denominator?

Answer 6

not exactly. but you follow the formula.
see https://www.khanacademy.org/math/differential-calculus/taking-derivatives/chain_rule/v/derivatives-of-sin-x-cos-x-tan-x-e-x-and-ln-x
for a brief intro.
why it is true is a bit involved
