b) 10 + (-2)3 -4 =
c) 12 – 1 + (-4)2 =
d) (-1)5 + 3 – 9 =
e) 18 – (+7) + 32 =
f) 6 + (-1)5 - 2 =
g) (-2)3 - 7 – (-1) =
h) (-5)3 - 1 + (-1)9 =
i) 50 - ( -10) + 23 =
j) (-2)3 + (-3)2 - 25 =

Answer 1

Resposta:

a)0

b)0

c)3

d)-11

e)43

f)-1

g)-12

h)-25

i)83

j)-37

Explicação passo a passo:

a) 5 + ( -3)2 + 1 =

$5 + ( -3)2 + 1 =\\5-6+1=\\0$

b) 10 + (-2)3 -4 =

$10 + (-2)3 -4 =\\10-6-4=\\0$

c) 12 – 1 + (-4)2 =

$12 – 1 + (-4)2 =\\12-1-8=\\3$

d) (-1)5 + 3 – 9 =

$(-1)5 + 3 – 9 =\\-5-6=\\-11$

e) 18 – (+7) + 32 =

$18 – (+7) + 32 =\\18-7+32=\\11+32=\\43$

f) 6 + (-1)5 - 2 =

$6 + (-1)5 - 2 =\\6-5-2=\\6-7=\\-1$

g) (-2)3 - 7 – (-1) =

$(-2)3 - 7 – (-1) =\\-6-7+1=\\-13+1=\\-12$

h) (-5)3 - 1 + (-1)9 =

$(-5)3 - 1 + (-1)9 =\\-15-1-9=\\-15-10=\\-25$

i) 50 - ( -10) + 23 =

$50 - ( -10) + 23 =\\50+10+23=\\50+33=\\83$

j) (-2)3 + (-3)2 - 25 =

$(-2)3 + (-3)2 - 25 =\\-6-6-25=\\-12-25\\-37$

espero ter ajudado :}
