Question

Which is equivalent to 3 cube root 125

Answer 1

Do you mean $3 \sqrt[3]{125}$ or $\sqrt[3]{125}$
remember that $\sqrt[n]{x^m}=x^\frac{m}{n}$
resolve the $\sqrt[3]{125}$ part first$\sqrt[3]{125}=$$\sqrt[3]{5^3}=$$5^\frac{3}{3}=$$5^1=$$5$

so
$3 \sqrt[3]{125}=3*5=15$ or $\sqrt[3]{125} =5$not sure which one you mean

Answer 2

Find a triple factor of 125

5 is your answer

5 x 5 x 5 = 125

25 x 5 = 125

125 = 125 (True)
