Question

value of x^2 + 1/x^2
​

Answer 1

Answer:

23

Step-by-step explanation:

Square both the sides

We get,

X^2+1/X^2+2X x 1/x=25

X^2 +1/X^2 =25-2=23

Answer 2

If x+1/x=5

Then find x^2+1/x^2

Squaring both the sided we get,

(x+1/x) = (5)^2

x^2+1/x^2 = 25

x^2+ 2×x×1/x + 1/x^2 =25

x^2+1/x^2 = 25-2=23
