Answer:
Hence proved
Step-by-step explanation:
x+1/x=2
->(x+1/x)square = 2 square
x^2+1/x^2+2=4
x^2+1/x^2=4-2
= 2
->x^2+1/x^2=2
(x^2+1/x^2)square = 2 square
x^4+1/x^4+2=4
x^4+1/x^4=4-2
= 2
->(x+1/x)^3=2^3
x^3+1/x^3+3(x+1/x)=8
x^3+1/x^3+3*2=8
x^3+1/x^3=8-6
x^3+1/x^3=2
x^2+1/x^2=2
x^3+1/x^3=2
x^4+1/x^4=2
Hence Proved
