1) x^2+1/x^2

2) x^4+1/x^4​

please answer me now

Answer 1

Answer:

x+1/x =8

x^2+1/x^2 =8*8=64

8*8*8=512

Answer 2

Answer:

(x+1/x)²=64

x²+1/x²+2=64

x+1/x²=62

(x²+1/x²)²=62²

x⁴+1/x⁴+2=62²

find square of 62

3844

x⁴+1/x⁴=3844-2

3842

answers are 62,3842

(x+1/x)²=x²+(1/x)²+2×x×1/x

x²+1/x+2

(x²+1/x²)=(x²)²+(1/x²)²+2×x²×1/x²

x⁴+1/x⁴+2

thanks a lot for marking me the brainliest

it'd help me a lot

I had squared both sides to get your answer
