Question

If $\sqrt[3]{372\times A}=12$, then find the value of $A$.

• A. $12$
• B. $24$
• C. $36$
• D. $6$

Answer 1

Answer: (B)

$24$

$\Rightarrow \sqrt[3]{372\times A}=12$

Cubing both the sides, we get

$\Rightarrow 72\times A={12}^3$

$\Rightarrow 72\times A=1728$

$\Rightarrow A=\frac{1728}{72}$

$\Rightarrow A=24$
