Question

please ans this question​

Answer 1

Answer:

3

Step-by-step explanation:

$(\sqrt{x} -\frac{1}{\sqrt{x}} )^2=x+\frac{1}{x}-2 X\sqrt{2}X\frac{1}{\sqrt{2}}=x+\frac{1}{x}-2$   ........(1)

Given,

x+(1/x)=11

so, from (1), we get

$(\sqrt{x} -\frac{1}{\sqrt{x}} )^2=11-2\\=>(\sqrt{x} -\frac{1}{\sqrt{x}} )^2=9\\=>(\sqrt{x} -\frac{1}{\sqrt{x}}=\bold{3} or -\bold{3}$

3 is given in options,

hence, 3 is the answer
