Me ajudem por favor

Answer 1

Resposta:

a) (52 + 82 – 18 – 7) x 2

(134-18-7)×2

(134-25)×2

109×2=

218

b) 9 + 8 + [49 + (36 : 2) – 3]

9+8[49+18+3]

9+8[67+3]

9+8+70=

17+70=

87

c) 5² + 8² – 18 – 7 x 2

25+64-18-14=

89-32=

57

d) (5² + 8² – 18 – 7) x 2

(25+64-18-7)×2

(89-32)×2

57×2=

114

e) 15 + [(7 – 100:100) + (16:4 – 4)] -2 + 10·3

14+[(7-1)+(4-4)]-2+30

14+[6+0]-2+30

14+6-2+30

20+28=

48

f) [(64 – 16·4) + (48·10 – 180)]·5

[(64-64)+(480-180)].5

[0+300].5

300.5=

1.500

Espero ter ajudado, bons estudos!
