Hy guys it is easy
you have to know that sign which indiacate square of base ^ question
(by square both side )
through algebric expression (a+b)^2
now
x^2+1^2/x^2=(26/5)^2
x^2+(1/x)^2+2×x×1/x=(26/5)^2
x^2+1^2/x^2=676/25-1
x^2+1^2/x^2=(676-25)/25
x^2+(1/x)^2=651/25ans
HOPE IT WILL HELP YOU PLZ MARK AS BRAINLIST ANSWER
