  56 x 31 - 5 x 56 x4

= 56 x31 - 56 x 20

= 56 x ( 31 - 20 )

= 56 x 11

= 616

Answer 2

56x31-5x56x4

=56x(31-5x4)

=56x(31-20)

=56x11

=616

Answer 3

= 56 x 31 - 56 x ( 5 x 4 ) 

= 56 x 31 - 56 x 20

= 56 x ( 31 - 20 )

= 56 x 11

= 616

Answer 4

\(56.31-5.56.4\)

\(=56\left(31-20\right)\)

\(=56.11\)

\(=616\)

Answer 5

56 x 31 - 5 x 56 x 4

= 56 x 31 -  56 x ( 5 x 4 )

=  56x 31 - 56 x 20

=       56 x ( 31 - 20 ) 

=         56 x  11 

=              616
