[latex]f a^{frac{{ n}}{{ m}}} implies sqrt[{ m}]{a^{ n}} qquad qquad sqrt[{ m}]{a^{ n}}implies a^{frac{{ n}}{{ m}}}\\ -----------------------------\\ (32x)^{frac{3}{4}}qquad 32=2^5implies (2^5x)^{frac{3}{4}}implies sqrt[4]{(2^5x)^3}implies sqrt[4]{2^{5cdot 3}x^{1cdot 3}} \\\ sqrt[4]{2^{15}x^3}implies sqrt[4]{2^{12+3}x^3}implies sqrt[4]{2^{12}2^3x^3}implies sqrt[4]{(2^3)^42^3x^3} \\\ 2^3sqrt[4]{2^3x^3}implies 8sqrt[4]{8x^3}[/latex]
