Question

tính bằng cách thuận tiện nhất :

50 x 9 x 3 x 2

Answer 1

\(50\times9\times3\times2\\=\left(50\times2\right)\times\left(9\times3\right)\\ =100\times27\\ =2700\)

Answer 2

50 x 9 x 3 x 2

= (50x2)x(9x3)

=100x27

=2700

Answer 3

= ( 50 x 2 ) x ( 9 x 3 )
= 100x 27 
= 2700

Answer 4

50 × 9 × 3 × 2

= (50 × 2) × (9 × 3)

= 100 × 27

= 2700
