Question

how to transform the quantity of the fifth root of x to the seventh power, to the third power into an expression with a rational exponen

Answer 1

$\bf a^{\frac{{ n}}{{ m}}} \implies \sqrt[{ m}]{a^{ n}} \qquad \qquad \sqrt[{ m}]{a^{ n}}\implies a^{\frac{{ n}}{{ m}}}\\\\ -----------------------------\\\\ \sqrt[5]{(x^7)^3}\implies \sqrt[5]{x^{7\cdot 3}}\implies \sqrt[5]{x^{21}}\implies x^{\cfrac{}{}\frac{21}{5}}$

Answer 2

I got the answer is = x^(21/5)
