Question

please solve question number 6 answer this question I mark him as briallianist

Answer 1

$(3 + \sqrt{3} )(2 + \sqrt{2} {)}^{2} \\ \\ expand \: using \: \\ {(a + b)}^{2} = {a}^{2} + 2ab + {b}^{2} \\ \\ (3 + \sqrt{3} )( {2}^{2} + 2 \times 2 \sqrt{2} + { \sqrt{2} }^{2} ) \\ \\ (3 + \sqrt{3} )(4 + 4 \sqrt{2} + 2) \\ \\ add \: the \: numbers \\ \\ (3 + \sqrt{3}) (4 + 2 + 4 \sqrt{2} ) \\ \\ (3+ \sqrt{3}) (6 + 4 \sqrt{2} ) \\ \\ multiply \: the \: bracket \: by \: using \: FOIL$

$3 × 6 +3× 4\sqrt{2} + 6 \sqrt{3} + \sqrt{3} \times 4 \sqrt{2}\\ \\ 18 + 12\sqrt{2} + 6 \sqrt{3} + 4 \sqrt{6} \\ \\ 55.1 6\: (approx)$

Answer 2

Assuming You asked for the 16th question. Below is a handmade script.

TIPS:

1. Simplifications require practice, patients, and a good idea of the Distributive law - i.e.. ab+ ac = a(b+c) further,   (a+b)(c+d) = ac+bc+ad+bd

2. This, in particular, equires some idea of what sq. roots are, how to take them as commons, etc..

If you still require clarification, please comment below.
