Exercise 13 Page 13

Distribute the exponent to the numerator and the denominator.

8/27

Practice makes perfect

To simplify the expression, first we need to distribute the exponent to both the numerator and the denominator.

(2/3)^3

PowQuot

(a/b)^m=a^m/b^m

2^3/3^3

CalcPow

Calculate power

8/27

We know that this is the most simplified version of the expression because there are no common factors between 8 and 27. If there were any common factors, we would need to further reduce our fraction.
