Explicação passo-a-passo:

$\mathsf{a)\:\sqrt{25a^4} = \sqrt{5^2a^4} = 5a^2}$

$\mathsf{b)\:\sqrt{4 \times 2} = \sqrt{8} = \sqrt{2.2^2} = 2\sqrt{2}}$

$\mathsf{c)\:\sqrt{16m^2} = \sqrt{4^2m^2} = 4m}$

$\mathsf{d)\:\sqrt{25 \times 4} = \sqrt{100} = \sqrt{10^2} = 10}$

$\mathsf{e)\:\sqrt{36 \times 4y^2} = \sqrt{144y^2} = \sqrt{12^2y^2} = 12y}$

$\mathsf{f)\:\sqrt{81a^2b^8} = \sqrt{9^2a^2b^8} = 9ab^4}$

$\mathsf{g)\:\sqrt{9 \times 2y^2} = \sqrt{3^22y^2} = 3y\sqrt{2}}$

$\mathsf{h)\:\sqrt{64a^2b^4c^8} = \sqrt{8^2a^2b^4c^8} = 8ab^2c^4}$
