Answer:
Explanation:
There is a possible issue in your question...
As written it can be interpreted in two ways
like this #1 :
or like this #2 :

VERSION #1
divide by the 2^x

to be able to get to the exponent you have to take "logs"
... look up the rules for logs ... log(ab) = log (a)+log(b) , log(a/b) = log(a)-log(b) etc.
if you take the logs of both sides the using the quotient rule and the exponent rule ....result the result is...

VERSION #2

25 x = 3(2^x)

This gets really nasty, and I assume that it is not the original problem..
