Correct Answer: $8 \sqrt{3}$

Solution : Given,
$\left(x-\frac{1}{x}\right)^2=12$
⇒ $x^2+\frac{1}{x^2}=12+2$
⇒ $x^2+\frac{1}{x^2}+2=12+2+2$
⇒ $x^2+\frac{1}{x^2}+2(x)(\frac{1}{x})=12+2+2$
⇒ $(x+\frac{1}{x})^2=16$
⇒ $(x+\frac{1}{x})=4$
And, $\left(x-\frac{1}{x}\right)=2\sqrt3$
Now,$\left(x^2-\frac{1}{x^2}\right)$
= $(x-\frac{1}{x})(x+\frac{1}{x})$
= $4\times2\sqrt3$
= $8\sqrt3$
Hence, the correct answer is $8\sqrt3$.
