Answer 1

Resposta:

2)[2+(2+2)⋅2]−5=

[2+(4)⋅2]−5=

[2+8]−5=

[10]−5=5

3)=(8−3)⋅2+2+6=

=(5)⋅2+2+6=

=10+2+6=

=12+6=

=18

4)3+(5−4)⋅5+10=

=3+(1)⋅5+10=

=3+5+10=

=8+10=

=18

5)=[(17)−6]⋅2+9+1=

=[11]⋅2+9+1=

=22+9+1=

=31+1=

=32

6)=5+2+(12−9)⋅2=

=7+(3)⋅2=

=7+6=

=13

7)=[14+(4⋅5−18)⋅3]⋅18:9=

=[14+(20−18)⋅3]⋅18:9=

=[14+(2)⋅3]⋅18:9=

=[14+6]⋅18:9=

=[20]⋅18:9=

=360:9=

=40

8)=(18−14)⋅3+(2−1)⋅6=

=(4)⋅3+(1)⋅6=

=12+6=

=18

9)=8+63:(3+6)+20=

=8+63:(9)+20=

=8+7+20=

=15+20=

=35

espero que te ajude amiguinho! boa sorte em seus estudos !
