Answer 1

Resposta:

7+5-3×2=6

75÷5+42-(4×3)=45

[(64-16×4)+(48×10-180)]×3=100

Answer 2

Resposta:

A) 6

B) 45

C) 900

Explicação passo-a-passo:

A) 7 + 5 - 3 × 2 =

7 + 5 - 6 =

12 - 6 =

= 6

B) 75 ÷ 5 + 42 - (4 × 3) =

15 + 42 - (4 × 3) =

15 + 42 - 12 =

57 - 12 =

= 45

C) [(64 – 16 x 4) + (48 x 10 – 180)] x 3 =

[(64 – 64) + (480 – 180)] x 3 =

[(0) + (300)] x 3 =

300 × 3 =

= 900
