Question : If $\left(x^2 - \frac{1}{x^2}\right) = 4 \sqrt{6}$ and $x>1$, what is the value of $\left(x^3 - \frac{1}{x^3}\right)?$
Option 1: $20 \sqrt{2}$
Option 2: $24 \sqrt{2}$
Option 3: $18 \sqrt{2}$
Option 4: $22 \sqrt{2}$
Correct Answer: $22 \sqrt{2}$
Solution : Given: $x^2 -\frac{1}{x^2} = 4\sqrt6$ Squaring both sides we get, ⇒ $x^4 +\frac{1}{x^4} - 2 = 96$ ⇒ $x^4 +\frac{1}{x^4}+2 = 98+2$ ⇒ $ (x^2+\frac{1}{x^2})^2 =100$ ⇒ $x^2 +\frac{1}{x^2} = 10$ ---------------(1) ⇒ $x^2 +\frac{1}{x^2} -2= 10-2$ ⇒ $(x-\frac{1}{x})^2=8$ ⇒ $(x-\frac{1}{x}) = 2\sqrt2$ ----------------(2)
