Answer 1

Resposta:

Explicação passo-a-passo:

A_

5+4^2-1=

5+(4x4)-1=

5+16-1=

5+15=20

B_

3^4-6+2^3=

(3x3x3x3)-6+(2x2x2)=

81-6+8=

75+8=83

C_

(4+3^2)-1=

4+3x3-1=

4+9-1=

4+8=12

D_

30+[6^2:(5-3)+1]=

30+[6x6:2+1]=

30+[36:2+1]=

30+[18+1]=

30+19=49

E_

[4^2+(5-3)]:(9-7)=

[4x4+2]:2=

[16+2]:2=

18:2=9

F_

50{15+[4^2:(10-2)+5x2]}=

50{15+[4x4:8+10]}=

50{15+[16:8+10]}=

50{15+[2+10]}=

50{15+12}=

50x27=1350
