Answer:

(512)^{-\frac{2}{9}}=\frac{1}{4}(512)−92=41

Step-by-step explanation:

Given : Expression (512)^{-\frac{2}{9}

To find : The value of the expression ?

Solution :

First we factor 512 so that we get to convert it into the power,

512=2\times 2\times 2\times 2\times 2\times 2\times 2\times 2\times 2512=2×2×2×2×2×2×2×2×2

512=2^9512=29

Substitute in expression,

(512)^{-\frac{2}{9}}=(2^9)^{-\frac{2}{9}}(512)−92=(29)−92

(512)^{-\frac{2}{9}}=(2)^{-\frac{2\times 9}{9}}(512)−92=(2)−92×9

(512)^{-\frac{2}{9}}=(2)^{-2}(512)−92=(2)−2

(512)^{-\frac{2}{9}}=\frac{1}{2^2}(512)−92=221

(512)^{-\frac{2}{9}}=\frac{1}{4}(512)−92=41
