Answer:2599

step by step explanation:

given:X-1/X=7

X^4+1/X^4=?

by squaring on both sides of equation 1

we get

(X-1/X)^2=(7)^2

( X - 1/X )^2 =49

(X + 1/X)^2 -4 =49

(X + 1/X)^2=53

X^2 + 1/X^2 +2 =53

X^2 + 1/X^2 =51

(X^2 + 1/X^2)^2 =(51)^2

X^4 + 1/X^4 +2 = 2601

X^4 + 1/X^4 = 2601 - 2

Therefore the answer is X^4+1/X^4 =2599
