Answer 1

Tính

A=12.194+6.437.2+3.369.4

B=1+5+9+13+...+57+61+65.2-26

Giải:A=12.194 + 6.2.437 + 3.4.369

=12.194+12.437+12.369

=12.(194+437+369)

=12.1000=12000

B=1+5+..............+57+61+65.2-26

=(1+61)+(5+57)+...........+(29+33) + 130-26

=62+62+...........+62+104

=62 x 8 + 104

=496+104=600
