Question

If K²+1/K²=51,find k

Answer 1

<br>

Hey

Here is your answer,

K^2 + 1 /k^2 = 51

K^2 + 1 = 51k^2

51k^2 - k^2 = 1

50k^2 = 1

K^2 = 1/50

K = +/- √1/50

K = +/- (1/5√2)

Hope it helps you!

Answer 2

K² + 1 / K² = 51

K² + 1 = 51K²

51K² - K² = 1

50k² = 1

K² = 1/50

K = √1/50 = √1 × 1 / 5 × 5 ×2.




K = 1/5√2
