Question : If $x^{4}+\frac{1}{x^{4}}=119$, then the value of $x-\frac{1}{x}$ is:
Option 1: 6
Option 2: 12
Option 3: 11
Option 4: 3
Correct Answer: 3
Solution : Given: $x^4+\frac{1}{x^4} = 119$ ⇒ $(x^2+\frac{1}{x^2})^2–2×x^2×\frac{1}{x^2} = 119$ ⇒ $(x^2+\frac{1}{x^2})^2–2 = 119$ ⇒ $(x^2+\frac{1}{x^2})^2 = 119+2 = 121$ ⇒ $x^2+\frac{1}{x^2} = \sqrt{121} = 11$ Now, $(x–\frac{1}{x})^2+2×x×\frac{1}{x} = 11$ ⇒ $(x–\frac{1}{x})^2+2 = 11$ ⇒ $(x–\frac{1}{x})^2 = 11–2 = 9$ ⇒ $x–\frac{1}{x} = \sqrt9 = 3$ Hence,
