Question

5 – Seguindo essas ordens acima resolva as expressões a seguir:
a) 5 ² : (5 + 1 – 1) + 4 . 2 =
c) 3² : (4 – 1) + 3. 2² =
d) 70 - [5 . (2² : 4) + 3²] =
e) 5² + 2³– 2 . (3 + 9) =
f) 25 + {3 ² 9 + [3² . 5 – 3 . (2³– 5 1 )]} =

Answer 1

a) 5^2 : 5 + 4 . 2
25 : 5 + 8
5 + 8
=13

c) 3^2 : 3 + 3.4
9 : 3 + 12
3 + 12
15

d) 70 - [5. (4 : 4) + 9]
70- [5. 1 + 9]
70- 14
56

e) 25 + 8 - 2 . 12
25 + 8 - 24
33 - 24
=9

f) 25 + {3^2 9+ [3^2 . 5 - 3. (8 - 5)}]
25 + {3^2 9+ [3^2 .5 - 3.3)}]
25+ {3^2 9+ [9.5 - 9)]}
25+ {9.9+ [45-9)]}
25+ {81 + 36)]}
25+ 117
=142
