Question

If
$x + \frac{1}{x} = 8$
Then, find the value of
${x}^{2} + \frac{1}{ {x}^{2} }$
First correct answer will be marked as brainliest...!!!

Answer 1

here is your answer!!!!!!!
x+1/x=8
square the both side
so x²+1/x²=64
when subtract -2
x²+1/x²-2=64-2
x²+1/x²=62+2
x²+1/x²=64

that's all

Answer 2

x+1/x=8

square the both side

so x²+1/x²=64

when subtract -2

x²+1/x²-2=64-2

x²+1/x²=62+2

x²+1/x²=64
