Question : If $\small x-\frac{1}{x}=2$, then the value of $x^{3}-\frac{1}{x^{3}}$ is:
Option 1: 15
Option 2: 2
Option 3: 14
Option 4: 11
Correct Answer: 14
Solution : Given: $\small x-\frac{1}{x}=2$ We know that $(a-b)^3=a^3-b^3-3ab(a-b)$ So, $(x-\frac{1}{x})^3=x^3-\frac{1}{x^3}-3(x-\frac{1}{x})$ Substituting the given values, we get ⇒ $2^3=x^3 - \frac{1}{x^3}-3(2)$ ⇒ $x^3 - \frac{1}{x^3}=14$ Hence, the correct answer is 14.
