Okay so first you have to simplify the problem so that would be
15^(x-4)+8=100

Okay so know that it's simplified now you need to do the distributive property.

So it would be
15x-60+8=100

Now subtract 8 from 100

15x-60=92

Now you add 60 to 92

15x=152

Now dive 152 by 15 and that is your answer

X=10.133
