​

Answer 1

Explicação passo-a-passo:

a) 32:(4.8)¹

32:32¹

32:32=1b) -3.4-4+[32:16.-99]

-3.4-4+[2.-99]

-3.4-4+-198

-12-4-198= -214

c)[24-12:(-2)²-7]:(9-5)

[24-12:4-7]:4

[24-3-7]:4

[14]:4= 3,5

d)(4/25).(8/27).(81/16)

32/675.81/16=

2.592/10.800÷8=324/1350÷27=12/50÷2=6/25

e){39-[196:(2)-4]+1600}

{39-[98-4]+1600}

{39-94+1600}=1545

f)32-[6²:(8-6)-2³]

32-[36:2-8]

32-[18-8]

32-10=22

g)1+2-[45+(9.5-3):2]

3-[45+(45-3):2]

3-[45+42:2]

3-[45+21]

3-66= -63

h)8+1-9:1

9-9=0

i)9+9:9-8.(-2)

9+1+16=26
