X
${x}^{2} - 1 = 3 \\ {x}^{2} = 1 + 3 \\ \\ {x}^{2} =4 \\ x = 2$

Aaley34: i think the ans should be 119

Aaley34: when you square both sides and use expansion and then repeat it again then you get 119

adici: But question was not proper display.so thats why reason i measured the only formula

$x - \frac{1}{x} = 3 \\ \\ {x}^{2} - 1 = 3x \\ \\ {x}^{2} = 3x + 1 \\ \\ x = \sqrt{3x + 1.} \\ \\$
Putting this value in x^4+1/x^4 ,we get

(√3x+1)^4 + 1/(√3x+1)^4
9x^2+6x+1 +1/9x^2+6x+1
(9x^2+6x+1)^2+1/9x^2+6x+1
81x^4+108x^3+54x^2+12x+2 / 9x^2+6x+1

Now it cannot be solved further.

Liked my answer mark it as brainliest .

Aaley34: from step 1 how did you reach step 2
