Answer 1

꧁Hello, how are you?꧂

$a) \: \: \sqrt{5} + \sqrt{5} + \sqrt{7} \\ 1 \sqrt{5} + 1 \sqrt{5} + \sqrt{7} \\ (1 + 1) \sqrt{5} + \sqrt{7} \\ 2 \sqrt{5} + \sqrt{7}$

$b) \: \: 10 \sqrt{11} - 3 \sqrt{3} + 4 \sqrt{11} \\ 14 \sqrt{11} - 3 \sqrt{3}$

$c) \: \: \sqrt{3} \times \sqrt{12} \\ \sqrt{36 } \\ 6$

$e) \: \: \sqrt{50} \\ \\ \sqrt{5 {}^{2} \times 2} \\ \\ \sqrt{5 {}^{2} } \sqrt{2} \\ \\ 5 \sqrt{2}$
