Question

1500x0+0x1500

792x2+792x7+792

Answer 1

\(1500\times0+0\times1500=0+0=0\)

\(792\times2+792\times7+792=\)

\(792\times\left(2+7+1\right)=7920\)

Answer 2

1500x0+0x1500=0

792x2+792x7+792

=792x2+792x7+792x1

=792x(2+7+1)

=792x10

=7920

Answer 3

1500x0+0x1500=0+0=0

792x2+792x7+792=792x2+792x7+792x1

                           =792(2+7+1)

                           =792x10

                           =7920

Answer 4

1500 x 0 + 0 x 1500

= 0 + 0 x 1500

= 0 x 1500

= 0

792 x 2 + 792 x 7 + 792

= 792 x ( 2 + 7 + 1 )

= 792 x 10

= 7920

ai k mình , mình k lại

Answer 5

1500x0+0x1500=1500x(0+0)=0

792x2+792x7+792=792x(2+7)+792=792x9+792=7128+792=7920

Answer 6

1500*0+0*1500=0

792*2+792*2+792=792*(2+2+1)=792*5=3960

Answer 7

1500x0+0x1500

=0+0

=0

792x2+792x7+792

=792x2+792x7+792x1

=792x(2+7+1)

=792x10

=7920
