Question

If x+1/x= 5 then find root x+ 1/root x

Answer 1

Answer:

I think that answer is 5/root of 5x-1

$\frac{5}{ \sqrt{5x - 1} }$

Answer 2

Answer:

$\sqrt{7}$

Step-by-step explanation:

$(\sqrt{x} + \frac{1}{\sqrt{x}})^{2} = x+\frac{1}{x}+2 \\ = 5+2\\ = 7\\ \sqrt{x} + \frac{1}{\sqrt{x}} = \sqrt{7}$
