d) 107-{27+(36-2x5)-[2+3x(4-2)]-1}=​

Answer 1

Resposta:

a) (21+3)+(32+5)+(48+3)+1=

24+37+51+1=

61+52=

113

b) 4+2x8-3x5-1

4+(16)-(15)-1=

4+1-1=

5-1=4

c)36+(5x4-3x6)x2-2x4=

36+(20-18)x2-2x4=

36+2x2-2x4=

36+4-8=

40-8=

32

d)107-{27+(36-2x5)-[2+3x(4-2)]-1}=​

107-{27+(26)-[2+3x2]-1}=

107-{27+26-[8]-1}=

107-{44}=
