Answer 1

Explicação passo-a-passo:

A) 72 - 5 x (27 : 3 - 6)

= 72 - 5 x (9 - 6)

= 72 - 5 x 3

= 72 - 15

= 57

B) (20 : 5 + 3) x 22

= (4 + 3) x 22

= 7 x 22

= 154

C) 33 : {10 + [6 : 3 + (1+2)] - 4}

= 33 : {10 + [6 : 3 + 3] - 4}

= 33 : {10 + [2 + 3] - 4}

= 33 : {10 + 5 - 4]

= 33 : {15 - 4}

= 33 : 11

= 3

D) 120 + {560 : [40 + (300 : 10)] - 19}

= 120 + {560 : [40 + 30] - 19}

= 120 + {560 : 70 - 19}

= 120 + {8 - 19}

= 120 - 11

= 109

E) 28 x [6 x (42 : 3 - 9)]

= 28 x [6 x (14 - 9)]

= 28 x [6 x 5]

= 28 x 30

= 840

F) 360 : {100 - [50 - (2 x 3 + 4)]} + 40

= 360 : {100 - [50 - (6 + 4)]} + 40

= 360 : {100 - [50 - 10]} + 40

= 360 : {100 - 40} + 40

= 360 : 60 + 40

= 6 + 40

= 46

G) (36 - 54 : 9) x 2

= (36 - 6) x 2

= 30 x 2

= 60

H) (64 : 8 - 2 x 3) x 10

= (8 - 6) x 10

= 2 x 10

= 20
