Question

Resolva as seguintes expressões numéricas :
a) √100 x {2³ - [4 x (7 x 2)⁰] x 2} +10¹
b) [(√169 - 4) x (1 +√25)] : (√49 - 1)
c)√121 - 100 +5 x (3+5)²
d) [(√169 - 4) x (1 + √25)] : (√49 - 1)

Answer 1

a) 10 x {8 - [4 x 1] x 2} + 10
    10 x {8 - 4 x 2} +10
    10 x 0 + 10
    10 

b) [(13 - 4) x (1 + 5)] : (7 - 1)
    [9 x 6] : 6
    54 : 6
    9

c) 11 - 100 + 5 x 64
    11 - 100 + 320
    231

d) [(13 - 4) x (1 + 5)] : (7 - 1)
    [9 x 6] : 6
    54 : 6
    9

Answer 2

a) 10 x {8 - [4 x 1] x 2} + 10
10 x {8 - 4 x 2} + 10
10 x {8 - 8} + 10
10 x 10 = 100

b) [(13 - 4) x (1 + 5)] : (7 - 1)
[9 x 6] : 6
54 : 6 = 9

c) 11 - 100 + 5 x 64
11 - 100 + 320 = 231

d) [(13 - 4) x (1 + 5)] : (7 - 1)
[9 x 6] : 6 = 9
