Explicação passo-a-passo:

Answer 2

a) 72-5(27÷3-6)=72-5(9-6)= 72-5(3)=72-15=57

b) (20÷5+3)*22= (4+3)*22= 154

c) 33÷{10+[6÷3+(1+2)]-4}= 33÷{10+[2+3]-4}=33÷{11}=3

d) 120+{560÷[40+(300÷10)]-19}= 120+{560÷[40+(30)]-19}=

120+{560÷[70]-19}=120+{8-19}= 120+{8-19}= 120-11= 109

e) 28[6(42÷3-9)]= 28[6(14-9)]= 28[6(5)]= 28[30]= 840

f) 360÷{100-[50-(2*3+4)]}+40= 360÷{100-[50-(10)]}+40= 360÷{100-[40]}+40= 360÷{60}+40= 6+40 = 46

g) (36+54÷9)2= (36+6)2= (42)2= 84

h) (64÷8-2*3)10= (8-6)10= 20

i) 46+[5+(42÷6-4) cade o outro colchete? = 46+[5+(12-4) = 46+[13= 59
