Question

If u can help pls do

Answer 1

Solution:-

$1. \: \: \: \: \: \: \: \large \: (10 + \sqrt{3} )(6 + \sqrt{2} )$

$\rightarrow \: 60 + 10 \sqrt{3} + 6 \sqrt{3} + \sqrt{6}$

$\rightarrow \: 60+ 16 \sqrt{3} + \sqrt{6}$

$2. \: \: \: \: \large {(3 + \sqrt{11}) }^{2} + {(3 - \sqrt{11} )}^{2}$

$\rightarrow 9 + 11 + 6 \sqrt{11} + 9 + 11 - 6 \sqrt{11}$

$\large\rightarrow \: 9 + 11 + 9 + 11$

$\large\rightarrow \: 40$

Answer:-

1. $\: 60+ 16 \sqrt{3} + \sqrt{6}$
2. 40
