Mathematics

$\displaystyle x\sqrt[7]{x}^2$

Step-by-step explanation:

According to the Definition of Rational Exponents [part II], we can rewrite this exponential expression as a radical:

$\displaystyle \sqrt[n]{a}^m = a^{\frac{m}{n}} \\ \\ x\sqrt[7]{x}^2 = x^{\frac{9}{7}} \\ \\ \\ [\sqrt[7]{x}^2][\sqrt[7]{x}^7] = x\sqrt[7]{x}^2$

I am joyous to assist you anytime.
