Question

radiciação alguém me ajuda
$\sqrt[5]{3} {}^{2} \times \sqrt[5]{3} {}^{3}$

$\sqrt{ {13}^{2} } \times 20 {}^{2}$

$\sqrt{49 \times 36 \times 25 = }$
​

Answer 1

a)

$\mathtt{\sqrt[5]{{3}^{2}}\times\sqrt[5]{{3}^{3}}=\sqrt[5]{{3}^{2}\times{3}^{3}}=\sqrt[5]{{3}^{5}}=3}$

b)

$\mathtt{\sqrt{{13}^{2}}\times{20}^{2}=13\times400=5200}$

c)

$\mathtt{\sqrt{49\times36\times25}=7\times6\times5=210}$
