Answer 1

Resposta:

h)20-{8+[3+(8-5)-1]+6} = (R:1) ... f) (10-4)-(9-8)+3= (R:8)g) 50-[37-(15-8)]= (R:20) ... b) { [ ( 18 – 3 ) + ( 7 + 5) – 2 ] + 5 } – 12 = (R:18)c) 65 – { 30 – [ 20 ... f)9+[4+2x(6-4)+(2+5)]-8 = (R:16)g) 50+{10-2x[(6+4:2)-(10-3)]} = (R:58) ... 5) - 8] . 2 } - 100 = ( R: 34) e) 80 - 5 . ( 28 - 6 . 4 ) + 6 - 3 . 4 = (R: 54) 9) Calcule a) 4 .
