Question

calcule usando a propriedade dos radicais

A)
$4 {}^{0.5}$
B)
$12 {}^{ \frac{12}{3} }$
C)
$25 {}^{ \frac{1}{2} }$
D)
$8 {}^{ \frac{1}{3} }$
​

Answer 1

A-

${4}^{0.5} = {4}^{ \frac{1}{2} } = \sqrt[2]{ {4}^{1} } = 2$

B-

${12}^{ \frac{12}{3} } = \sqrt[3]{ {12}^{12} } = 12 \times 12 \times 12 \times 12 = 20736$

C-

${25}^{ \frac{1}{2} } = \sqrt[2]{ {25}^{1} } = 5$

D-

${8}^{ \frac{1}{3} } = \sqrt[3]{ {8}^{1} } = 2$
