Answer 1

-2 ·√25√7 + 3√196√3 - 3√ 169√7 + 2√361√3
= - 2 · 5·√7  + 3 · 14√3 - 3 ·13·√7 + 2· 19·√3 
= -10√7  + 42√3  - 39√7 + 38√3 
= -  49√7  + 80√3

Answer 2

$-2 \sqrt{175} +3 \sqrt{588} -3 \sqrt{1183} +2 \sqrt{1083} = \\ =-2 \cdot 5 \sqrt{7} +3 \cdot 14 \sqrt{3} -3 \cdot 13 \sqrt{7} +2 \cdot 19 \sqrt{3} = \\ =-10 \sqrt{7} +42 \sqrt{3} -39 \sqrt{7} +38 \sqrt{3} = -49 \sqrt{7} +80 \sqrt{3}$
