Answer 2

Answer:

527

Step-by-step explanation:

x+1/x=5

squaring on both sides

(x+1/x)^2=5^2

x^2 + (1/x)^2 + 2*x*1/x = 25

x^2 + 1/x^2 + 2 = 25

x^2 + 1/x^2 = 25-2

x^2 + 1/x^2 = 23

again squaring on both sides

(x^2 + 1/x^2)^2 = 23^2

(x^2)^2 + (1/x^2)^2 + 2*x^2*1/x^2= 529

x^4 + 1/x^4 + 2 = 529

x^4 + 1/x^4 = 529-2

x^4 + 1/x^4 = 527
