Question #09fd4

Answer 1

See below

Explanation:

This answer will assume `log` is referring to the natural logarithm

Chain rule for composite functions:

`(fg(x))'=f'(g(x))g'(x)`

`(log^4 x)'=4log^3 x 1/x=(4log^3 x)/x`

If `log` is referring to the `log` of base `10`, then the derivative is:

`(4ln^3 x)/(xln^4 10)`
