Which equation justifies why 93-3√9?
Simora [160]

Considering the conversion from exponent to radical, the equation that justifies why the expression 9^{\frac{1}{3}} = \sqrt[3]{9} is correct is.

(9^{\frac{1}{3}})^{3} = 9^{\frac{3}{3}} = 9

<h3>How is the conversion from exponent to radical realized?</h3>

The conversion of rational exponents to radical notation is modeled by:

a^{\frac{n}{m}} = \sqrt[m]{a^n}

In this problem, the expression is:

9^{\frac{1}{3}} = \sqrt[3]{9}

And the equation that shows that this is correct is:

(9^{\frac{1}{3}})^{3} = 9^{\frac{3}{3}} = 9
