Question

5supra1*(7supra10+1supra2)+[(3supra8+2supra3)*6supra1-3supra4]*12supra33​

Answer 1

5/1•(7/10+1/2(amplificam cu 5)+[(3/8+2/3)•6-3/4]•12/33=

=5•(7+5/10)+(3/8•6+2/3•6-3/4)•4/11=

=5•12/10+(18/8+12/3-3/4)•4/11=

=12/2+(9/4+4(amplificam cu 4)-3/4)•4/11=

=6+(9+16-3/4)•4/11=

=6+(25-3/4)•4/11=

=6+22/4•4/11=

=6+2=

=8
