$\sqrt{27} = \sqrt{9 \times 3} = 3 \sqrt{3}$

$\sqrt{98} = \sqrt{49 \times 2} = 7 \sqrt{2}$

$\sqrt{80} = \sqrt{16 \times 5} = 4 \sqrt{5}$

$\sqrt{160} = \sqrt{10 \times 16} = 4 \sqrt{10}$

$\sqrt{432} = \sqrt{36 \times 12 } = 6 \sqrt{12}$

$\sqrt{675} = \sqrt{25 \times 27} = \sqrt{25 \times 9 \times 3} = (5 \times 3) \sqrt{3} = 15 \sqrt{3}$

$3 \sqrt{12} = 3 \sqrt{3 \times 4} = (3 \times 2) \sqrt{3} = 6 \sqrt{3}$

$2 \sqrt{18} = 2 \sqrt{9 \times 2} = (2 \times 3) \sqrt{2} = 6 \sqrt{2}$

$4 \sqrt{24} = 4 \sqrt{6 \times 4} = (4 \times 2) \sqrt{6} = 8 \sqrt{6}$

$7 \sqrt{75} = 7 \sqrt{25 \times 3} = (7 \times 5) \sqrt{3} = 35 \sqrt{3}$

$\frac{3}{2} \sqrt{200} = 1 \frac{1}{2} \sqrt{100 \times 2} = (1.5 \times 10) \sqrt{2} = 15 \sqrt{2}$

$0.2 \sqrt{300} = 0.2 \sqrt{100 \times 3} = (0.2 \times 10) \sqrt{3 } = 2 \sqrt{3}$
