Question

o valor da Expressão é

Answer 1

$\ \ \sqrt[3]{\frac{60000\times0,00009}{0,0002}} \\ \\= \sqrt[3]{\frac{6\cdot10^4\times9\cdot10^{-5}}{2\cdot10^{-4}}} \\ \\= \sqrt[3]{\frac{6\times9\cdot10^{4+(-5)-(-4)}}{2}} \\ \\= \sqrt[3]{\frac{6\times9}{2}\cdot10^{4+(-5)-(-4)}} \\ \\= \sqrt[3]{27\cdot10^{4-5+4}} = \sqrt[3]{27\cdot10^3}\\ \\ =3\cdot10^1\\ \\=3\cdot10\\ \\=30$
