Question

calcule as expressões numéricas:

a) 8 + 4 - (-3)³ - 1 =
b) 25 - (-3)² + 1 - 5 =
c) 8 - (-4)³ - 1 + 3 =
d) [-(-2)]³ + (-4)³ - (-2)^{-4} + 0³ =
e) 2 - (-6)² - $5^{4}$ - 2 + $-2^{5}$

Answer 1

a) 38
b) 12
c) 74
d) -55,9375
e) -693

Answer 2

a)8+4-(-27)-1
   8+4+27-1=38
b)25-(+9)+1-5
    25-9+1-5=12
C)8-(-64)-1+3
    8+64-1+3=74
D)|2|³+(-64)+1/16+0
   8-64+1/6=
MMC=16
128/16-1024/16+1/16=-895/16
E)2-36-625-2-32
-36-625-32=-693
