Question

if x-1/x=0 then x^4+1/x^4​

Answer 1

Answer:x^4+1/x^4=2

Step-by-step explanation:

x-1/x=0

(x-1/x)²=0

x²+1/x²-2=0

x²+1/x²= 2

(x²+1/x²)²= (2)²

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

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

x^4+1/x^4=2

Answer 2

IF x-1/x=0

SQUARING BOTH SIDE

[x-1/x]²=0

x²+1/x²-2=0

x²+1/x²=2

AGAIN SQUARING BOTH SIDE

[x²+1/x²]²=4

x⁴+1/x⁴+2=4

x⁴+1/x⁴=2 ANSWER
