Answer 2

Explicação passo-a-passo:

$a) \sqrt{2}. \sqrt{32} = \\ \sqrt{2} \times \sqrt{32} \\ \sqrt{2 \times 32} \\ \sqrt{64} \\ \sqrt{2} \times \sqrt{32} \\ \sqrt{64} \\ \sqrt{8 {}^{2} } \\ 8 \\ \sqrt{64} \\ 8 \\ resposta \\ 8 \\ \\ b) \sqrt{48} \div \sqrt{12} = \\ \sqrt{48} \div \sqrt{12} \\ \sqrt{48 \div 12} \\ \sqrt{4} \\ \sqrt{48} \div \sqrt{12} \\ \sqrt{4} \\ \sqrt{2 {}^{2} } \\ 2 \\ \sqrt{4} \\ 2 \\ resposta \\ 2 \\ \\ c)3 \sqrt{2}.3 \sqrt{4} = \\ 3 \sqrt{2} \times 3 \sqrt{4} \\ \sqrt{4} \\ \sqrt{2 {}^{2} } \\ 2 \\ 3 \sqrt{2} \times 3 \sqrt{4} \\ 3 \sqrt{2} \times 3 \times 2 \\ 9 \sqrt{2} \times 2 \\ 18 \sqrt{2} \\ 3 \sqrt{2} \times3 \times 2 \\ 18 \sqrt{2} \\ resposta \\ 18 \sqrt{2} \\ \\ d) \sqrt{50} \div \sqrt{2} = \\ \sqrt{50} \div \sqrt{2} \\ \sqrt{50 \div 2} \\ \sqrt{25} \\ \sqrt{50} \div \sqrt{2} \\ \sqrt{25} \\ \sqrt{5} {}^{2} \\ 5 \\ \sqrt{25} \\ 5 \\ resposta \\ 5 \\ \\ e) \sqrt{3}. \sqrt{6} = \\ \sqrt{3} \times \sqrt{6} \\ \sqrt{3 \times 6} \\ \sqrt{18} \\ \sqrt{3} \times \sqrt{6} \\ \sqrt{18} \\ \sqrt{9 \times 2} \\ \sqrt{3 {}^{2} } \times 2 \\ \sqrt{3 {}^{2} } \sqrt{2} \\ 3 \sqrt{2} \\ \sqrt{18} \\ 3 \sqrt{2} \\ resposta \\ 3 \sqrt{2} \\ \\ f)4 \sqrt{32} \div 4 \sqrt{2} = \\ 4 \sqrt{32} \div 4 \sqrt{2} \\ 1 \sqrt{32} \sqrt{2} \\ 32 \sqrt{2} \\ \sqrt{32 \times 2} \\ \sqrt{64} \\ 1 \sqrt{32 } \sqrt{2} \\ \sqrt{64} \\ \sqrt{8}{}^{2} \\ 8 \\ \sqrt{64} \\ 8 \\ resposta \\ 8$
