Question

$\sqrt3{125} =$
a. 11.2
b. $\frac{125}{3}$
c. 5
d. 25

Explanation:

Step1: Recall cube root definition

A cube root of a number \( x \) is a number \( y \) such that \( y^3 = x \). So we need to find \( y \) where \( y^3 = 125 \).

Step2: Test possible values

Check \( 5^3 \): \( 5\times5\times5 = 125 \). So \( \sqrt[3]{125}=5 \).

Answer:

C. 5
