Explicação passo a passo:

$\mathsf{a)\:\sqrt{50} = \sqrt{25.2} = \sqrt{5^2.2} = 5\sqrt{2}}$

$\mathsf{b)\:\sqrt{40} = \sqrt{4.10} = \sqrt{2^2.10} = 2\sqrt{10}}$

$\mathsf{c)\:\sqrt{300} = \sqrt{100.3} = \sqrt{10^2.3} = 10\sqrt{3}}$

$\mathsf{d)\:\sqrt{72} = \sqrt{36.2} = \sqrt{6^2.2} = 6\sqrt{2}}$
