Question

Tính theo cách hợp lý phép : 25×6×4×8×125 

Answer 1

25.6.4.8.125

=(25.4).(125.8).6

=100.1000.6

=100000.6

=600000

Answer 2

\(25\cdot6\cdot4\cdot8\cdot125\)

\(=25\cdot4\cdot6\cdot8\cdot125\)

\(=100\cdot6\cdot1000\)

\(=100000\cdot6\)

\(=600000\)

Answer 3

\(25\times6\times4\times8\times125=\left(25\times4\right)\times6\times\left(125\times8\right)\)

\(100\times6\times1000=600\times1000\)\(=600000\)

Answer 4

25.6.4.8.125

=(25.4).6.(125.8)

=100.6.1000

=(100.1000).6

=100000.6

=600000

ok nha
