1..
[tex] \sqrt{32} - 3 \sqrt{2} + \sqrt{98} \\ = 4 \sqrt{2} - 3 \sqrt{2} + 7 \sqrt{2} \\ = 8 \sqrt{2} [/tex]
2..
[tex]5 \sqrt{45} + \sqrt{80} - 2 \sqrt{25} \\ = 5 \sqrt{9 \times 5} + \sqrt{16 \times 5} - 2(5) \\ = 15 \sqrt{5} + 4 \sqrt{5} - 10 \\ = 19 \sqrt{5} - 10[/tex]
3...
[tex] \sqrt{75} + 3 \sqrt{48} - \sqrt{108} \\ = \sqrt{25 \times 3} + 3 \sqrt{16 \times 3} - \sqrt{36 \times 3} \\ = 5 \sqrt{3} + 12 \sqrt{3} - 6 \sqrt{3} \\ = 11 \sqrt{3} [/tex]
4...
[tex]2 \sqrt{100} - 2 \sqrt{36} \\ = 2(10) - 2(6) \\ = 20 - 12 \\ 8[/tex]
5...
[tex]3 \sqrt{8} + 4 \sqrt{32} - 2 \sqrt{98} \\ = 3 \sqrt{4 \times 2} + 4 \sqrt{16 \times 2} - 2 \sqrt{49 \times 2} \\ = 6 \sqrt{2} + 16 \sqrt{2} - 14 \sqrt{2} \\ = 8 \sqrt{2} [/tex]
