1900 x 5 + 1900 x 4 + 1900
= 1900 x 5 + 1900 x 4 + 1900 x 1
= 1900 x ( 5 + 4 + 1 )
= 1900 x 10
= 19000
\(1900.5\) + \(1900.4\) + \(1900\)
= \(1900\) . \(\left(5+4+1\right)\)
= \(1900.10\)
= \(19000\)
Ta có :
900 x 5 + 1900 x 4 + 1900
= 1900 x 5 + 1900 x 4 + 1900 x 1
= 1900 x ( 5 + 4 + 1 )
= 1900 x 10
= 19000
Đap số : 19000
1900 x 5 + 1900 x 4 + 1900
= 1900 x 5 + 1900 x 4 + 1900 x 1
= 1900 x ( 5 + 4 + 1 )
= 1900 x 10
= 19000
1900 x 5 + 1900 x 4 + 1900
= 1900 x 5 + 1900 x 4 + 1900 x 1
= 1900 x ( 5 + 4 + 1 )
