Question

Rationalize the denominator of 3 - 2*root2/3 + 2*root2

Answer 1

Ans.

$\frac{3 - 2 \sqrt{2} }{3 + 2 \sqrt{2} } \\ = \frac{(3 - 2 \sqrt{2} )(3 - 2 \sqrt{2}) }{(3 + 2 \sqrt{2} )(3 - 2 \sqrt{2} )} \\ = \frac{9 - 12 \sqrt{2} + 8}{9 - 8} \\ = \frac{17 - 12 \sqrt{2} }{1} \\ = 17 - 12 \sqrt{2}$

I HOPE THAT THIS HELPS YOU.
