Answer 1

Answer:

hOPE IT HELPS

Step-by-step explanation:

IF 1/X=3, THEN X= 1/3

SO, GIVEN IS  $x^{2} +1/x^2$

WE SHALL NOW APPLY VALUE OF X IN THE GIVEN EQUATION,

I.E.       $( 1/3)^2+1/ (1/3)^2$

TAKING LCM AND SOLVIVNG WE GET,

10/9*9/1  = 10

I THINK IM CORRECT.....

Hey mate . You still have confusion.

x²+1/x²+2×x×1/x = 3²...... [(a+b)² = a²+b²+2ab].
