Option 1: 11
Option 2: 64
Option 3: 30

Question : If $x^2-\sqrt{7} x+1=0$, then what is the value of $x^5+\frac{1}{x^5} ?$
Option 1: $19 \sqrt{7}$
Option 2: $21 \sqrt{7}$
Option 3: $25 \sqrt{7}$
Option 4: $27 \sqrt{7}$
Correct Answer: $19 \sqrt{7}$
Solution : Given: $x^2-\sqrt{7} x+1=0$ Dividing by $x$, we get: ⇒ $x+\frac{1}{x}=\sqrt{7}$ Now, Squaring both sides, we get: ⇒ $(x+\frac{1}{x})^2=(\sqrt{7})^2$ ⇒ $x^2+\frac{1}{x^2}+2=7$ ⇒ $x^2+\frac{1}{x^2}=5$ Similarly, Cubing both sides, we get: ⇒ $(x+\frac{1}{x})^3=(\sqrt{7})^3$ ⇒ $x^3+\frac{1}{x^3}+3(x\times\frac{1}{x})(x+\frac{1}{x})=7\sqrt7$ ⇒ $x^3+\frac{1}{x^3}+3\sqrt 7=7\sqrt7$ ⇒ $x^3+\frac{1}{x^3}=4\sqrt7$ Now, $x^5+\frac{1}{x^5}=(x^3+\frac{1}{x^3})\times(x^2+\frac{1}{x^2})-(x+\frac{1}{x})$ = $4\sqrt7\times5-\sqrt7$ = $20\sqrt7-\sqrt7$ =
