Question

ME AJUDEM RAPIDO!!!!!!!!!!!!!!!!!!! PLEASE!!!!!!!!!!!!!!

Answer 1

Explicação passo-a-passo:

$\sqrt[3]{250} = \sqrt[3]{5 {}^{3} \times 2} = \sqrt[3]{5 {}^{5} } \times \sqrt[3]{2} = 5 \sqrt[3]{2} \\ \\ \sqrt[4]{128} = \sqrt[4]{2 {}^{7} } = \sqrt[4]{2 {}^{4 + 3} } = \sqrt[4]{2 {}^{4} } \times \sqrt[4]{2 {}^{3} } = \sqrt[4]{2 {}^{3} } = 2 \sqrt[4]{8} \\ \\ \sqrt{5 {}^{2} \times 12 {}^{3} } = \sqrt{25 \times 12 {}^{3} } = \sqrt{5 {}^{2} \times 12 {}^{3} } = \sqrt{5 {}^{2} \times 12 {}^{1 + 2} } = \sqrt{5 {}^{2} \times 12 \times 12 {}^{2} } = \sqrt{5 {}^{2} } \times \sqrt{12 {}^{2} } \times \sqrt{12} = 5 \times 12 \sqrt{12 } = 60 \sqrt{12} = 60 \sqrt{2 {}^{2} \times 3} = 60 \sqrt{2 {}^{2} } \times \sqrt{3} = 60 \times 2 \sqrt{3} = 120 \sqrt{3}$
