Question

Rationalize. 1. 3-2√2 _ 3+2√2​

Answer 1

Answer:

17+12√2

Step-by-step explanation:

$\frac{3 - 2 \sqrt{2} }{3 + 2 \sqrt{2} }$

now we have to multiply 3-2√2 by both

$\frac{(3 - 2 \sqrt{2}) \times (3 - 2 \sqrt{2} ) }{(3 + 2 \sqrt{2}) \times (3 - 2 \sqrt{2}) }$

$\frac{9 + 8 + 12 \sqrt{2} }{9 - 8}$

$\frac{17 + 12 \sqrt{2} }{1}$

$17 + 12 \sqrt{2}$
