2011 - EXERCÍCIO 01

Resolva as seguintes expressões numéricas:

a) 3 . ( 4 +5 . 7) + 3 . 2 =
b) [ 2 . 4² - ( 5 . 3 - 7º)] . 2 =
c) ( 7 - 5 )² : ( 5 - 7)² =
d) ( 7 + 5 ) : 4 + ( 8 - 6 ) : 2 =
e) [(3 . 4 - 5 . 6º) : (15 - 8 )] . 3=

Agora que todos já postaram suas respostas, segue a resolução:

a)

3.(4+35) +6=
=3.39 + 6=
= 117+6=
=123

b)

[2.16-(15-1)].2=
=[32-14].2=
=18.2=
=36

c)

( 7 - 5 )² : ( 5 - 7)² =
=(2)² : (-2)²=
=4:4=
=1

d)

( 7 + 5 ) : 4 + ( 8 - 6 ) : 2 =
=12:4+2:2=
=3+1=
=4

e)

[(3 . 4 - 5 . 6º) : (15 - 8 )] . 3=
