Question

3) Calcule as potências:
a) (+7)2 =
b) (+4)2 =
c) (+3)2 =
d) (+5) =
e) (+2) =
f) (+3)3 =
g) (+2)4 =
h) (+2)5 =
i) (-5)2 =​

Answer 1

a) (+7)2 =

7.7 = 49

b) (+4)2 =

4.4 = 16

c) (+3)2 =

3.3 = 9

d) (+5) = 5

e) (+2) = 2

f) (+3)3 =

3.3.3 = 27

g) (+2)4 =

2.2.2.2 = 16

h) (+2)5 =

2.2.2.2.2 = 32

i) (-5)2 =

(-5).(-5) = 25
