Question

x²+1/x²=6, find the value of x^4/1x^4​

Answer 1

Answer:

On squaring both sides,

$( {x}^{2} + \frac{1}{ {x}^{2} } ) { }^{2} = {6}^{2}$

we know (a+b)^2=a^2 +b^2+2ab

x^4+1/x^4+2=36

x^4+1/x^4=34

Answer 2

given x^2+1/x^2=6

squaring on both sides

we get

x^4+1/x^4+2=36

x^4+1/x^4=36-2

= 34

hope this helps you
