Question

What is the cube root of $36\times 48$?

• A. 14
• B. 12
• C. 6
• D. 24

Answer 1

The correct option is B 12

$36\times 48=6^2\times 8\times 6$
$=3^2\times 2^2\times 2^3\times 2\times 3$
$=3^3\times 2^3\times 2^3$
Thus, $\sqrt[3]{336\times 48}=\sqrt[3]{33^3\times 2^3\times 2^3}=2\times 2\times 3=12$
