Question

Verifica egalitatile:
a). [(2+4)*20:12+30*3]:50=[(245:5-132:4)*5]:25





b)5+5*[5*5+5*(5+5*5)]=450




​

Answer 1

Răspuns:

a)(6*20:12+30*3)=[(49-34)*5]:25

=(120:12+90)=(15*5):25

=(10+90)=75:25

=100=3(F)

5+5*[5*5+5*(5+25)]=450

5+5*(5*5+5*30)=450

5+5*(25+150)=450

5+5*175=450

5+775=450

780=450(F)
