Crack it Guyzzzzz......!!!!

Answer 1

Step-by-step explanation:

2.) Add

$\sqrt{3} + 6 \sqrt{7} + 2 \sqrt{3 } + 5 \sqrt{7} \\ = 3 \sqrt{3} + 11 \sqrt{7}$

3.) simplify

$\frac{25 \sqrt{13} }{17 \sqrt{13} } \\ \\ = \frac{25}{17}$

4.) Subtract

$5 - 8 \sqrt{2} - 7 \sqrt{2} + 12 \\ = 17 - 15 \sqrt{2}$
