Rewrite the expression with a rational exponent as a radical expression.
Vilka [71]

Answer:

\sqrt{5}

Step-by-step explanation:

The "power rule" tells us that to raise a power to a power, just multiply the exponents

so

(a^{m})^{n}=a^{m*n}

we have

(5^{\frac{3}{4}})^{\frac{2}{3}}

Applying the "power rule"

(5^{\frac{3}{4}})^{\frac{2}{3}}=5^{\frac{3}{4}*\frac{2}{3}}=5^{\frac{1}{2}}=\sqrt{5}
