Question

1) Simplifique os radicais:

a)
$\sqrt[3]{x {}^{3 = } }$

b)
$\sqrt{2 {}^{4} } {3 {}^{2} } =$

c)
$\sqrt[15]{2 {}^{10 = } }$

d)
$\sqrt{512 = }$
​

Answer 1

Explicação passo-a-passo:

a) x

b) $\sqrt{2^4} * \sqrt{3^2} = 2^2 * 3 = 4 * 3 = 12$

c) $\sqrt[15]{2^{10}} = 2^{\frac{10}{15}} = 2^\frac{2}{3}$

d)$\sqrt{512} = \sqrt{2^9} = \sqrt{2^8 * 2^1} = 2^4\sqrt{2} = 16\sqrt{2}$
