Answer 1

Answer:

hope it will help you ^_^

Answer 2

$\red{ i) 25\sqrt{2} + 6 \sqrt{2}}$

$= (25+6)\sqrt{2}$

$\green { = 31\sqrt{2} }$

$\red{ ii) 8\sqrt{5} - 2 \sqrt{5}}$

$= (8-2)\sqrt{5}$

$\green { = 6\sqrt{5} }$

$\red{ iii) 9\sqrt{3} - 3 \sqrt{3}}$

$= (9-3)\sqrt{3}$

$\green { = 6\sqrt{3} }$

$\red{ iv) 12\sqrt{6} + 18\sqrt{6}}$

$= (12+18)\sqrt{6}$

$\green { = 30\sqrt{6} }$

$\red{ v) 17\sqrt{11} + 3 \sqrt{11}}$

$= (17+3)\sqrt{11}$

$\green { = 20\sqrt{11} }$

$\red{ vi) 7\sqrt{3} - 6 \sqrt{3}}$

$= (7-6)\sqrt{3}$

$\green { = \sqrt{3} }$
