Question

If x - 1/x =0 , then the value of x^4 + 1/x4​

Answer 1

Answer:x2+x−1=0⇒x = 0 does not satisfy the equation.

⇒x2+x−1x=0, x ≠ 0

⇒x+1−1x=0

⇒x−1x=−1

Squaring ,x2+1x2−2⋅x⋅1x=1  

⇒x2+1x2=1+2=3

Squaring,x4+1x4+2⋅x2⋅1x2=32=9

⇒x4+1x4=9−2=7

Answer 2

Answer:

answer is 2 for the given problem
