Question

find the value of x+1/x if x^2+1/x^2=11
​

Answer 1

Answer:

Step-by-step explanation: let us take

x^2+1/x^2 = 11

>   x^2+1 = 11x^2

>   10x^2 = 1

>    x^2 =1/10 -------- eq 1

>    x = root of 1/10

from eq 1

>    (1/10) + 1 / (1/10)

>     (10+1/10) / (1/10)

>     11

so answer is 11
