tính nhanh:

24x62+48x19

Answer 1

24 x 62 + 48 x 19

=24 x 62 + 24 x 2 x 19

=24 x ( 62 + 2 x 19)

= 24 x ( 62 +38)

= 24 x 100

= 2400

Answer 2

24X62+48X19

=24X62+(24X2)X19

=24X62+24X(2X19)

=24X62+24X38

=24X(62+38)

=24X100=2400

Answer 3

24 x 62 + 48 x 19 = 24 x 62 + 24 x 38

                           = 24 x ( 62 + 38 )

                            = 24 x 100 = 24000

Answer 4

   24 x 62 + 48 x 19

= 24 x 62 + 24 x 2 x 19

= 24 x 62 + 24 x 38

= 24 x ( 62 + 38 )

= 24 x 100

= 2400 

Answer 5

Ta có : 24 x 62 + 48 x 19 

= 24 x 62 + 24 x 2 x 19

= 24 x 62 + 24 x 38

= 24 x (62 + 38) 

= 24 x 100

= 2400 

Answer 6

24x62+48x19

=24x62+24x2x19

=24x(62+38)

=24x100

=2400

Answer 7

24 x 62 + 48 x 19

= 24 x 62 + 24 x 2 x 19

= 24 x (62 + 38)

= 24 x 100

= 2400

Answer 8
