Question

raiz quadrada de 125 elevado a 3? resposta completa, por favor.

Answer 1

$( \sqrt{125} ) {}^{3} = \sqrt{125} \times \sqrt{125} \times \sqrt{125} \\ = 5 \sqrt{5 } \times 5\sqrt{5} \times 5 \sqrt{5} \\ = 25 \sqrt{25} \times 5 \sqrt{5} \\ = 25 \times 5 \times 5 \sqrt{5} \\ = 625 \sqrt{5}$

Answer 2

$(\sqrt{125} ) {}^{3} = (125 {}^{1 \div 2} ) {}^{3} \\ = (125 {}^{0.5} ) {}^{3 } = 62.5 {}^{3 } = 244.140$
