Answer 2

Explicação passo-a-passo:

4 - Resolva as divisões abaixo.

a) (– 18 ) : (+ 6 ) =-3

b) (– 35 ) : (– 5 ) = 7

c) (+ 70 ) : (+ 7 ) =10

d) (+ 45 ) : (– 9 ) = -5

e) (– 49 ) : ( + 7 ) = -7

5 - . Calcule as potências:

a) (+7)² =49

b) (+4)² =16

c) (+3)² =9

d) (–6)³ =-216

e) (–4)³ =-64

f) (–6)² =36

6 - Determine as Raízes:

a) − √4 =-2

b) √25 =5

c) − √36 =-6

d) √ 81 =9

e) √ 169 =13
