Question

Determine o valor de:

$\sqrt{100}$
$\sqrt[8]{256}$
$+ \sqrt{25}$
$- \sqrt{144}$
$\sqrt[3]{ - 8}$
$3 \sqrt{16}$
​

Answer 1

Explicação passo-a-passo:

$\sqrt{100} = \sqrt{10 \times 10} = 10 \\ \sqrt[8]{256} = \sqrt[8]{2 {}^{8} } = 2 \\ + \sqrt{25} = + \sqrt{5 \times 5} = + 5 \\ - \sqrt{144} = - \sqrt{12 \times 12} = - 12 \\ \sqrt[3]{ - 8} = \sqrt[3]{( - 2) \times ( - 2) \times ( - 2) } = - 2 \\ \sqrt[3]{16} = \sqrt[3]{2 {}^{3} \times 2} = 2 \sqrt[3]{2}$

Answer 2

Explicação passo-a-passo:

$a) \sqrt{100} = 10$

$b) \sqrt[8]{256} = 2$

$c) \sqrt{25} = 5$

$d ) - \sqrt{144} = - 12$

$e) \sqrt[3]{ - 8} = - 2$

$f)3 \sqrt{16} = 3.4 = 12$
