If x4 + 1/x4=322, the then x - 1/x
is?​

Answer 1

Answer:

u have not mentioned question correctly

Answer 2

Step-by-step explanation:

we have x4+1/x4=322

let x2=4, then x4+1/x4=42+1/4242+1/42= 42+1/42-24 1/4 -24 .1/4

putting X square =4, we get

xpower4+1/x power4= X square+1/x square-2

now, xsquare+1/X square=x square +1/X square.2x.1/X+ 2x.1/X

(x-1/2)=2.so

x power four +1/X power four= [(x-1/X)+2] square -2=322

[(x-1/x) square+2] square=322

[(x-1/X) square+2] square=18square

[(x-1/X) square]=16

x-1/X=4
