tính bằng cách thuận tiện nhất

Answer 1

25 x 432 x 4

=( 25 x 4 )x 432

= 100 x 432

= 43 200

Answer 2

456 x 200 - 456 x 100

= 456 x ( 200 - 100)

= 456 x 100

= 45 600

Answer 3

25×432×4=25×4×432=100×432=43200. 456×200-456×100=456×(200-100)=456×100=45600

Answer 4

25 x 432 x 4

= 25 x 4 x 432

= 100 x 432

= 43200

Answer 5

456 x 200 - 456 x 100

= 456 x ( 200 - 100 )

= 456 x 100

= 45600
