1) Calcule o valor das expressões:
a) 4²- 10 + (2³ - 5) = (R: 9)
b) 30 – (2 + 1)²+ 2³ = (R: 29)
c) 30 + [6² : ( 5 – 3) + 1 ] = (R: 49)
d) 20 – [6 – 4 x( 10 - 3²) + 1] = (R: 17)
e) 50 + [ 3³ : ( 1 + 2) + 4 x 3] = (R: 71)
f) 100 –[ 5² : (10 – 5 ) + 2⁴ x 1 ] = (R: 79) g) [ 4² + ( 5 – 3)³] : ( 9 – 7)³ = (R: 3) h) 7²+ 2 x[(3 + 1)² - 4 x 1³] = (R: 73)
i) 25 + { 3³ : 9 +[ 3² x 5 – 3 x (2³- 5¹)]} = (R: 64)
2) Calcule as expressões:
a) ( 8 : 2) . 4 + {[(3² - 2³) . 2⁴ - 5⁰] . 4¹}= (R:76)
b) ( 3² - 2³) . 3³ - 2³ + 2² . 4² = ( R:83)
c) ( 2⁵ - 3³) . (2² - 2 ) = (R: 10)
d) [2 . (10 - 4² : 2) + 6²] : ( 2³ - 2²) = ( R:10)
e) (18 – 4 . 2) . 3 + 2⁴ . 3 - 3² . ( 5 – 2) = (R: 51)
f) 4² . [2⁴ : ( 10 – 2 + 8 ) ] + 2⁰ = (R: 17)
g) [( 4² + 2 . 3²) + ( 16 : 8)² - 35]² + 1¹⁰ - 10⁰ = (R : 9)
h) 13 + ( 10 – 8 + (7 – 4)) = (R: 18)
i) (10 . 4 + 18 – ( 2 . 3 +6)) = (R:46)
j) 7 . ( 74 – ( 4 + 7 . 10)) = (R: 0)
k) ( 19 : ( 5 + 3 . 8 – 10)) = (R : 1)
l) (( 2³ + 2⁴) . 3 -4) + 3² = (R: 77)
m) 3 + 2 . ((3²- 2⁰) + ( 5¹ - 2²)) + 1 = (R: 22)
