When we raise a fraction to a power, we raise both the numerator and the denominator to that power.
So, to evaluate (-3/4)^3, we can cube both the numerator and the denominator separately:
(-3/4)^3 = (-3)^3 / (4)^3
Simplifying the numerator and denominator, we get:
(-3/4)^3 = -27 / 64
Therefore, (-3/4)^3 is equal to -27/64.
