Question

Calcule as potências:
A) $3^{2}$

B)$(- 2)^{3}$

C)$(\frac{1}{2}) ^{3}$

D)$( \frac{3}{2} ) ^{4}$

E) $(10) ^{3}$

Answer 1

A) 3² = 9

B) (-2)³ = - 8

C) (1/2)³ =   1
                    8
D) (3/2)^4 =     81
                       16
E) (10)³ = 1.000

Answer 2

.
$a) \\ 3^2=9 \\ \\ b) \\ (-2)^3=-8 \\ \\ c) \\ ( \frac{1}{2} )^3= \frac{1}{8} \\ \\ d) \\ ( \frac{3}{2})^4= \frac{81}{16} \\ \\ e) \\ (10)^3=1000$
