In this case I believe you would add 25 to both sides. The -25 +25 would cancel out and then +25 would be on the right.

When you multiply a base with an exponent by a base with an exponent, you add the exponents together. (But you can only combine the exponents when the bases are the same)
For example:
(they have the same base of x)
(you can't combine the exponents because they have different bases of y and x)
When you have a negative exponent, you move the base with the negative exponent to the other side of the fraction to make the exponent positive.
For example:
or
or
Add the exponents together
Make the exponent positive
