Question

Tính nhanh :

2 x 3 x 4 x 5 x 50 x 25

Answer 1

`= 2 xx 5xx 50 xx 4 xx 25 xx 3`

`= 500 xx 100 xx 3`

`= 150000`

Answer 2

\(=2\cdot50\cdot4\cdot25\cdot3\cdot5=150000\)

Answer 3

\(2\times3\times4\times5\times50\times25\)

\(=\left(2\times50\right)\times\left(25\times4\right)\times3\times5\)

\(=100\times100\times15\)

\(=150000\)

Answer 4

2 x 3 x 4 x 5 x 50 x 25 

= (2 x 50)x(3 x 15)x(4 x 25)
= 100 x 45 x 100

= 450.000
