Resposta:

Espero ter ajudado :3

Explicação passo-a-passo:

a. 25+{12+[2-(8-6)+2]} --> (8-6)=2--->[2-2+2]-->2-->25+2=7

b.{[(18-3)+(7+5)-2]+5}-12-->(18-3)=15-->(7+5)=12-->15+12=27-2=25+5=30-12=18

c.65-[30-{20-(10-1+6)+1}]-->10-1+6=15-->20-15+1=6-->30-6+1=25-->65-25=40

d.45+[15-](10-8)+(7-4)-0]-4}-->10-8=2->7-4=3-->2+3=5->5-3=2->15-2-4=9->45-9=36
