$\sqrt{245} =\sqrt{49*5} = \sqrt{7^{2}*5 } = 7\sqrt{5}$

$\sqrt{300} =\sqrt{100*3} = \sqrt{10^{2}*3 } = 10\sqrt{3}$

$\sqrt{320} =\sqrt{64*5} = \sqrt{8^{2}*5 } = 8\sqrt{5}$

$\sqrt{252} =\sqrt{36*7} = \sqrt{6^{2}*7 } = 6\sqrt{7}$

$\sqrt{720} =\sqrt{144*5} = \sqrt{12^{2}*5 } = 12\sqrt{5}$

$\sqrt{588} =\sqrt{196*3} = \sqrt{14^{2}*3 } = 14\sqrt{3}$

$\sqrt{675} =\sqrt{225*3} = \sqrt{15^{2}*3 } = 15\sqrt{3}$

$\sqrt{648} =\sqrt{324*2} = \sqrt{18^{2}*2 } = 18\sqrt{2}$
