Question

Resolva as expressões:

25-[18-(10-4+2)-5}+16-7+4)=

[8+[4-(16-13-3)+(20-6-10)]-16]+5=   

Answer 1

Olá

vamos lá

=25-[18-(10-4+2)-5}+16-7+4)
=25-[18-(6+2)-5}+9+4)
=25-[18-8-5}+13)
=25-[10-5}+13)
=25-5+13
=20+13
=33


[8+[4-(16-13-3) + (20-6-10)] -16 ] +5
=8 +[4+4]-16]+5
=8+8-16+5
=5

Answer 2

a)25-[18-(10-4+2)-5}+16-7+4)=

25-[18-(8)-5}+16-7+4)=

25-[18-13}+16-7+4)=

25-[5}+16-7+4)=

20+9+4 =29+4=33

b) [8+[4-(16-13-3)+(20-6-10)]-16]+5=  

[8+[4-(16-16)+(20-6-10)]-16]+5=  

[8+[4+(20-6-10)]-16]+5=  

[8+[4+(4)]-16]+5=  

[8+8]-16]+5=  

16-16+5 =5
