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
