The Problem:

.

Step-by-step explanation:

Based on your choices I think you mean:

.

The equivalent exponential form is:

Take the fourth of both sides:

( There is two answer because it was even powered.)

Simplify:

Add 1 on both sides.

Since the base of logarithm can only be postive not including 1, then the answer is just x=3. As x=-1 gives the base as x-1=-1-1=-2.
