Question

if x = 3 + 2√2, √x - 1/√x​

Answer 1

$x = 3 + 2 \sqrt{2} \\ \frac{1}{x} = \frac{1}{3 + 2 \sqrt{2} } \\ by \: rationalizing \: denominator \: we \: get \\ \frac{1}{x} = 3 - 2 \sqrt{2} \\ x + \frac{1}{x} = 6 \\ x + \frac{1}{x} - 2 = 4 \\ ( { \sqrt{x} - \frac{1}{ \sqrt{x} } })^{2} = 4 \\ \sqrt{x} - \frac{1}{ \sqrt{x} } =± 2$
