For this case we must simplify the following expression:
We rewrite the expression:
We eliminate common terms:
For division of powers of the same base, the same base is placed and the exponents are subtracted:
By definition of properties of powers and roots we have:
So:
Answer:

First you do
82+67 = 149
Take that answer and minus it by 180
180-149 = 31
