To simplify these expressions, we can use the properties of exponents and the fact that we can represent different bases as powers of the same base where applicable.
-
First, express 27, 9, and 81 in terms of base 3:
, , .
So we can rewrite the expression as: -
Factor outfrom the numerator: Thus, -
Factorout of the numerator:
So the simplified results are:
