Question

Guys pls solve step by step fast pls

Answer 1

Step-by-step explanation:

$a) \: \: Multiply \: ( \sqrt{5} - 3 \sqrt{3} ) \: and \: ( \sqrt{6} - 3 \sqrt{2} )$

$( \sqrt{5} - 3 \sqrt{3} ) \times ( \sqrt{6} - 3 \sqrt{2} )$

$\scriptsize\sqrt{5} ( \sqrt{6} - 3 \sqrt{2} ) - 3 \sqrt{3} ( \sqrt{6} - 3 \sqrt{2} )$

$\sqrt{30} - 3 \sqrt{10} - 3 \sqrt{18} - 9 \sqrt{6}$

$b) \: \: Add \: 2√2 \: and \: \sqrt{2} - 3 \sqrt{3}$

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

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

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

$Or \: \: \: 3( \sqrt{2} - \sqrt{3})$
