Answer» make me brainlistExplanation:Answer:(512)^{-\frac{2}{9}}=\frac{1}{4}(512)−92=41Step-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=2×2×2×2×2×2×2×2×2512=2^9512=29Substitute 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 |
