plz someone tell.​

Answer 1

Answer:

x$x^{2} + 1/x^2=23\\x^2/x^2=23$

Step-by-step explanation:

By cutting them we will recieve the answer as 23.

Answer 2

Answer:

X² + 1/x² =23

adding 2 on both sides

X² + 1/x² + 2 =23 +2

we know that,

(a+b)² = a²+b²+2ab

So,

(x+1/X)² = 25

(x+1/X)² = (5)²

power 2 is cancel out

X+1/X = 5
