The Answer of Simplify each expression. Assume that all variables represent positive real numbers.
(a) $(-3)^{-3}$
(b) $\left(8 x^{3}\right)^{2 / 3}$
(c) $\left(\frac{27}{125}\right)^{-1 / 3}$

Simplify Each Expression (−3)−3(-3)^{-3}(−3)−3 (B) (8x3)2/3\left(8 x^{3}\right)^{2 / 3}(8x3)2/3 (C) (27125)−1/3\left(\frac{27}{125}\right)^{-1 / 3}(12527​)−1/3

Simplify Each Expression $(-3)^{-3}$ (B) $\left(8 x^{3}\right)^{2 / 3}$ (C) $\left(\frac{27}{125}\right)^{-1 / 3}$
