Use the rule:
is equivalent to .
is equivalent to
.
We want to make the exponent of a become 1. To do that we raise
both sides to the power, the reciprocal of the power
to which a is now raised to:
Multiply those exponents and get a to the 1 power:
That's technically the answer but we need to simplify it:
We write 25 as .
We write as
Multiply those exponents:
