4 x 113 x 25 - 5 x 112 x 20
= 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
= 11 300 - 11 200
= 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
4 x 113 x 25 - 5 x 112 x 20
= ( 4 x 25 ) x 113 - ( 5 x20) x112
= 100 x 113 - 100x112
= 100

\(=4\cdot25\cdot113-5\cdot20\cdot112\)
\(=100\cdot113-100\cdot112\)
\(=100\cdot\left(113-112\right)\)
\(=100\cdot1=100\)
4×113×25-5×112×20=?
Giúp mình với nha làm đúng mình tim nha
