    $\sqrt{32}=\sqrt{16.2}=4\sqrt{2}$
    $\sqrt{128}=\sqrt{64.2}=8\sqrt{2}$
    $\sqrt{288}=\sqrt{144.2}=12\sqrt{2}$
    $\sqrt{12}=\sqrt{4.3}=2\sqrt{3}$
    $\sqrt{147}=\sqrt{49.3}=7\sqrt{3}$
    $\sqrt{363}=\sqrt{121.3}=11\sqrt{3}$
    $\sqrt{125}=\sqrt{25.5}=5\sqrt{5}$
    $\sqrt{405}=\sqrt{81.5}=9\sqrt{5}$
    $\sqrt{96}=\sqrt{16.6}=4\sqrt{6}$
    $\sqrt{384}=\sqrt{64.6}=8\sqrt{6}$
    $\sqrt{63}=\sqrt{9.7}=3\sqrt{7}$
    $\sqrt{343}=\sqrt{49.7}=7\sqrt{7}$
    $\sqrt{1000}=\sqrt{100.10}=10\sqrt{10}$
