Answer 1

Resposta:

1)A)

${2}^{6} = 2 \times 2 \times 2 \times 2 \times 2 \times 2 = 64$

B)

${3}^{4} = 3 \times 3 \times 3 \times 3 = 81$

C)

${4}^{3} = 4 \times 4 \times 4 = 64$

D)

${5}^{3} = 5 \times 5 \times 5 = 125$

2)A)

$\sqrt{49} = 7$

B)

$\sqrt[3]{27} \\ 3 \sqrt{3 {}^{2} } \times \sqrt{3 } \\ 3 \sqrt{3 {}^{2} } \sqrt{3 } \\ 3 \times 3 \sqrt{3 } \\ 9 \sqrt{3}$

C)

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