Answer 1

$a)\\\\ \sqrt{8} + \sqrt{32}+\sqrt{72}-\sqrt{50} \\\\ \sqrt{2.4}+\sqrt{2.16} + \sqrt{2.36}-\sqrt{2.25}\\\\ 2\sqrt{2}+4\sqrt{2}+6\sqrt{2}-5\sqrt{2}\\\\ 7\sqrt{2}$

$b)\\\\ \sqrt{20} -\sqrt{24}+\sqrt{125}-\sqrt{54}\\\\ \sqrt{4.5}-\sqrt{4.6}+\sqrt{5.25}-\sqrt{9*6}\\\\ 2\sqrt{5}-2\sqrt{6}+5\sqrt{5}-3\sqrt{6}\\\\ 7\sqrt{5}-5\sqrt{6}$

$c)\\\\ \sqrt{80}-\sqrt{45}\\\\ \sqrt{16.5}-\sqrt{9.5} \\\\ 4\sqrt{5}-3\sqrt{5}\\\\ \sqrt{5}$

$d)\\\\ \frac{\sqrt{32}}{\sqrt{2} } +\frac{\sqrt{27} }{\sqrt{3} } \\\\ \frac{\sqrt{2.16}}{\sqrt{2} } +\frac{\sqrt{9.3} }{\sqrt{3} } \\\\ \frac{4\sqrt{2}}{\sqrt{2} } +\frac{3\sqrt{3} }{\sqrt{3} } \\\\ 4+3=7$

$e)\\\\ \sqrt{3.25}.\sqrt{2.75}\\\\ 5\sqrt{3.2.75} \\\\ 5\sqrt{2.3.3.25}\\\\ 5.5.3\sqrt{2}\\\\ 75\sqrt{2}$
