Question

12^(15)*d^(15)=36^(15)

Answer 1

d = 3

Explanation:

You can just divide 12^15 to the other side.

Now you have d^15=3^15

So d = 3

(cause 3^15 = 3^15)

Answer 2

`12^(15)\cdot d^(15)~~ = ~~36^(15)\implies (12\cdot d)^(15)=36^(15)\implies (12d)^(15)=36^(15) \\\\\\ 12=36\implies d=\cfrac{36}{12}\implies d=3`
