Question

If x+1/x=5 evaluate x2+1/x2​

Answer 1

Answer:

x+1/x =5

x+1 = 5x

4x =1

x= 1/4

put this value in

x^2 + 1/x^2

1/4)^2 +1/ (1/4)^2

{(1/16) +1 } /(1/16)

(17/16) ÷ 1/16 = 17

Answer 2

Answer:

1.0625

Step-by-step explanation:

$\frac{x + 1}{x} = 5$

$x + 1 = 5x$

$5x - x = 1$

$x = \frac{1}{4}$

After putting this value, we get:

$\frac{ {x}^{2} + 1}{ {x}^{2} } = \frac{ {4}^{2} + 1}{ {4}^{2} } = \frac{16 + 1}{16} = \frac{17}{16} = 1.0625$

Hence, solved....
