How to solve for R in T= P * (R+1)^n?

Question

How do I move the slove for R?

Answer 1

T = P * (R+1)^n

Divide by P:
T/P = (R+1)^n

Take the nth root of both sides:
(T/P)^(1/n) = R+1

Subtract 1:
(T/P)^(1/n) - 1 = R

There you are,

R = (T/P)^(1/n) - 1

Answer 2

T= P * (R+1)^n

(R+1)^n = T/P

n*ln(R+1) = ln(T/P)

ln(R+1) = ln(T/P)/n

(R+1) = (T/P)^1/n

R = [(T/P)^1/n] -1
