Explicație pas cu pas:

$\sqrt{63} = \sqrt{9*7} =\sqrt{9} *\sqrt{7} = 3\sqrt{7}$

$\sqrt{96} = \sqrt{16*6} =\sqrt{16} *\sqrt{6} = 4\sqrt{6}$

$\sqrt{125} = \sqrt{25*5} =\sqrt{25} *\sqrt{25} = 5\sqrt{5}$

$\sqrt{108} = \sqrt{36*3} =\sqrt{36} *\sqrt{3} = 6\sqrt{3}$

$\sqrt{149} = \sqrt{49*3} =\sqrt{49} *\sqrt{3} = 7\sqrt{3}$

$\sqrt{275} = \sqrt{25*11} =\sqrt{25} *\sqrt{11} = 5\sqrt{11}$

$\sqrt{180} = \sqrt{36*5} =\sqrt{36} *\sqrt{5} = 6\sqrt{5}$

$\sqrt{150} = \sqrt{25*6} =\sqrt{25} *\sqrt{6} = 5\sqrt{6}$

$\sqrt{242} = \sqrt{121*2} =\sqrt{121} *\sqrt{2} = 11\sqrt{2}$

$\sqrt{200} = \sqrt{100*2} =\sqrt{100} *\sqrt{2} = 10\sqrt{2}$

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

$\sqrt{363} = \sqrt{121*3} =\sqrt{121} *\sqrt{3} = 11\sqrt{3}$

$\sqrt{288} = \sqrt{144*2} =\sqrt{144} *\sqrt{2} = 12\sqrt{2}$

$\sqrt{450} = \sqrt{225*2} =\sqrt2{25} *\sqrt{2} = 15\sqrt{2}$

$-\sqrt{120} = -\sqrt{4*30} =-\sqrt{4} *\sqrt{30} = -2\sqrt{30}$

$-\sqrt{128} = -\sqrt{64*2} =-\sqrt{64} *\sqrt{2} = -8\sqrt{2}$

$-\sqrt1800} = -\sqrt{900*2} =-\sqrt{900} *\sqrt{2} = -30\sqrt{2}$

$-\sqrt{5000} = -\sqrt{2500*2} =-\sqrt{2500} *\sqrt{2} = -50\sqrt{2}$
