Question

resolva o radicais f)3√8 g)3√27 h)3√125 i)5√243​

Answer 1

Explicação passo-a-passo:

$3 \sqrt{8} = 3 \sqrt{2 {}^{2} \times 2 } = 3 \times 2 \sqrt{2} = 6 \sqrt{2}$

$3 \sqrt{27} = 3 \sqrt{3 \times 3 {}^{2} } = 3 \times 3 \sqrt{3} = 9 \sqrt{3}$

$3 \sqrt{125} = 3 \times \sqrt{5 {}^{2} \times 5} = 3 \times 5 \sqrt{5} = 15 \sqrt{5}$

$5 \sqrt{243} = 5 \sqrt{9 {}^{2} \times 3} = 5 \times 9 \sqrt{3} = 45 \sqrt{3}$
