How would I solve for x?

-----

Hi there...

Two hints/tips for you to solve this equation.

Nr.1. 

----------

First of all reverse the order so that "X" always ends up on the left side.

----------

Nr.2. 

----------

Square out the exponential value.

(Example...: "(2^16)=(4^8)=(16^4)=(256^2)=(256*256)=?"

----------

The rest is simple math.

I hope that helped a bit?

Kind regards

3^15 is just a normal number.

Add 4 to both sides.

then

divide both sides by -2

then

use your calculator to got the answer.
