Question : If $\left(x^2+\frac{1}{x^2}\right)=6$ and $0<x<1$, what is the value of $x^4-\frac{1}{x^4}$?
Option 1: $24\sqrt{2}$
Option 2: $-24\sqrt{2}$
Option 3: $-12\sqrt{10}$
Option 4: $12\sqrt{10}$
Correct Answer: $-24\sqrt{2}$
Solution : Use (a – b)2 = (a + b)2 – 4ab So, $(x^2-\frac{1}{x^2})^2 = (x^2+\frac{1}{x^2})^2 -4$ ⇒ $(x^2-\frac{1}{x^2})^2 = 6^2 -4$ ⇒ $(x^2-\frac{1}{x^2}) = - \sqrt {32}\ \ \ [\because 0<x<1]$ Also, $x^4 - \frac1{x^4} = (x^2+\frac{1}{x^2})(x^2-\frac{1}{x^2})$ ⇒ $x^4 - \frac1{x^4} = - 6

Question : If $a^2+1=9a$ and $a\neq0$, then the value of $a^2+\frac{1}{a^2}$ is:
Option 1: 81
Option 2: 18
Option 3: 79
Option 4: 83
Correct Answer: 79
Solution : Given: $a^2+1=9a, a\neq0$ Dividing both sides by $a$, we get $a+\frac{1}{a}=9$ Squaring both sides, we get $a^2+\frac{1}{a^2}+2×a×\frac{1}{a}=81$ ⇒ $a^2+\frac{1}{a^2}=81-2$ $\therefore a^2+\frac{1}{a^2}=79$ Hence, the correct answer is 79.
