x^2+1/x^2=p^2-2=81-2=79
now (x^2+1/x^2)((x^2+1/x^2)=x^4+1+1+x^4
=> 79×79-2=x^4+1/x^4
6241-2=6239=x^4+1/x^4
hope u like this.. please mark it as a brainliest answer

⇒ x+1 / x = 9
⇒ x+1 = 9x
⇒ 1 = 9x-x
⇒ 1= 8x
⇒ 1/8 = x ......(i)
∴ x^4 +1 / 2^4
⇒(1/8)^4 +1 / 16
⇒ 1 / 4096 + 1 / 16
⇒ 1/ 4096 + 256 / 4096
⇒ 257 / 4096 Ans ..
