Answer 1

resposta

essa demoro

Explicação passo a passo:

a) 2+8-3-5+15

10-3-5+15

7-10

=3

b)12+[35-(10+2)+2]

12+[35-12+2]

12+[35-14]

12+21

=33

c)[(12+3x2)/8+5x3]/6

[(21x2)/8+5x3]/6

42/8+5x3/6

5,25+15/6

20,25/6

=3,375

d)37+[-25-(-11+19-4)]

37+[-25(-11+15)]

37+[25-(-4)]

37+[25+4]

37+29

=66

e)60/{2x[-7+18/(-3+12)]}-[7x(-3)-18+9-2)+1]

60/{2x[7+18/9)]}-[7x-3-18/-2+1)]

60/{2x7+2}-[7x-3+9+1]

60/{14+23}-[7x-3+9+1]

60/9-[-21+9+1]

6,6-[-21+10]

6,6--21+10

6,6+21+10

27,6+10

=37,6

f)-8+{-5+[(8-120+(13+12)}-10}

-8+{-5+[4+25]-10}

-8+{-5+28-10}

-8+{23-10}

-8+13

8-13=5
