Question

The value of $x$ which satisfies the equation $\frac{x^2}{4}=\frac{6}{x}$ is:

• A. $2.59$
• B. $2.88$
• C. $3.03$
• D. $3.89$
• E. $8.00$

Answer 1

Answer: (B)

$2.88$

The given equation can be simplified as

$\frac{x^2}{4}=\frac{6}{x}$

$\Rightarrow x^3=6\times 4=24$
$\Rightarrow x=\sqrt[3]{324}=2.88$
