Question

if
${x}^{2} + \frac{1}{ {x}^{2} } = 2 \\ \\ \\ so \: find \: the \: value \: of \\ \\ \\ \sqrt{x} + \frac{1}{ \sqrt{x} }$
plz.... it's very urgent​

Answer 1

Hii its tom85

(1/x + x)^2 = x^2 + 1/x^2 + 2

(1/x + x)^2 = 4

(1/x + x)= + 2 and -2

(1/sqrt x + sqrt x)^2 = 1/x + x + 2

(1/sqrt x + sqrt x)^2 = 4

(1/sqrt x + sqrtx)=+2 , -2
