Question

1) Calcule as potências:
a) 4 6 =
b) (- 1,4) 2 =
c) (¾ ) 3 =
d) ( - 8) 3 =
e) (502) 0 =

Answer 1

Resposta:

a)

${4}^{6} = 4 \times 4 \times 4 \times 4 \times 4 \times 4 = 4096$

b)

$( { - 1.4})^{2} = ( - 1.4) \times ( - 1.4) = 1.96$

c)

$( { \frac{3}{4} })^{3} = \frac{3}{4} \times \frac{3}{4} \times \frac{3}{4} = \frac{27}{64}$

d)

$( { - 8})^{3} = ( - 8) \times ( - 8) \times ( - 8) = - 512$

e)

${502}^{0} = 0$
