4 x 113 x 25 - 5 x 112 x 20

= 4 x 25 x 113 - 5 x 20 x 112

= 100 x 113 - 100 x 112

= 100 x (113 - 112)

= 100 x 1

= 100

   4 x 113 x 25 - 5 x 112 x 20 

= 4 x 25 x 113 - 5 x 20 x 112

= 100 x 113 - 100 x 112

= 100 x (113 - 112)

= 100 x 1 

= 100

Cách 1: 4 x 113 x 25 - 5 x 112 x 20

= (25 x 4) x 113 - (5 x 20) x 112

= 100 x 113 - 100 x 112

= 11300 - 11200

= 100

Cách 2: 4 x 113 x 25 - 5 x 112 x 20

= (25 x 4) x 113 - (5 x 20) x 112

= 100 x (113 - 112)

= 100 x 1

= 100

5 x 217 x 20 - 4 x 215 x 25 

= 1085 x 20 - 4 x 215 x 25

= 21700 - 4 x 215 x 25

= 21700 - 860 x 25

= 21700 - 21500

= 200

\(5.217.20-4.215.25\)

\(=\left(5.20\right).217-\left(4.25\right).215\)

\(=100.217-100.215\)

\(=100.\left(217-215\right)\)

\(=100.2=200\)

Nhớ k cho mình nhé! thank you!!!
