Which of the following is equivalent to<br> (5) 3<br> O 54<br> O 54<br> 05<br> O V5

IrinaK [193]

Answer:

D. $\sqrt[3]{5^7}$

Step-by-step explanation:

The formula for this conversion is:

$a^\frac{x}{n}=\sqrt[n]{a^x}$

Substitute the values you currently have.

$5^\frac{7}{3}=\sqrt[n]{a^x}$

Since we know that

a = 5

x = 7

n = 3

Fill the square root with this.

$5^\frac{7}{3}=\sqrt[3]{5^7}$
