Question

Find dy/dx if f(x) = (x + 1)^2x.

Answer 1

a. 2xln(x + 1)
b. 2ln(x +1) + (2x/x+1)
c. 2x(x + 1)(2x -1)
d. [2ln(x + 1) + (2x/x + 1)](x + 1)^2x

Answer 2

my work is as follows:

((x+1)^2x) (ln(x+1)) (2)

Answer 3

2ln(x+1)(x+1)^2

Answer 4

i dont know what to do from here

Answer 5

what is the first step you did?

Answer 6

the first step should be to take the natural log of both sides of\[y=(x+1)^{2x}\]try that and tell me what you get

Answer 7

i used the formula
