1.a. [tex] \sqrt{80} = \sqrt{16 * 5} = \sqrt{4^{2} * 5} = \sqrt{4^{2} } \sqrt{5} = 4 \sqrt{5} [/tex]
b. [tex] \sqrt{108} = \sqrt{36 * 3} = \sqrt{6^{2} * 3} = \sqrt{6^{2} } \sqrt{3} = 6 \sqrt{3} [/tex]
2.a. [tex]9 \sqrt{2} - 5 \sqrt{18} - 2 \sqrt{2} = 9 \sqrt{2} - 15 \sqrt{2} - 2 \sqrt{2} = -8 \sqrt{2}[/tex]
b.[tex]4 \sqrt{3} - \sqrt{12} + \sqrt{27} = 4 \sqrt{3} - 2 \sqrt{3} + 3 \sqrt{3} = 5 \sqrt{3}[/tex]
