Correct Answer: 9602

Solution : Given:
$\left(x+\frac{1}{x}\right)=10$
Squaring both sides, we get:
⇒ $(x+\frac{1}{x})^2=10^2$
⇒ $x^2+\frac{1}{x^2}=100-2 = 98$
Squaring both sides, we get:
⇒ $(x^2+\frac{1}{x^2})^2=98^2$
⇒ $x^4+\frac{1}{x^4}=9604-2$
$\therefore x^4+\frac{1}{x^4}=9602$
Hence, the correct answer is 9602.
