Question

Q 1. If x + 1/x = 9, then find the value of x square + 1 / x square ​

Answer 1

Answer:

Consider (x – 1/x) = 9

Squaring on both the sides, we get

[x – (1/x)]2 = 32

x2 – 2 (x) (1/x) + (1/x2) = 9

x2 – 2 + (1/x2) = 9

Therefore, x2 + (1/x2) = 9 + 2 = 11

Answer 2

Answer:

x^2+1/x^2=79
