Bài 1 :
\(2010.3+2010.6+2010\)
\(=2010.3+2010.6+2010.1\)
\(=2010.\left(3+6+1\right)\)
\(=2010.10=20100\)
\(2.134.5\)
\(=2.5.134\)
\(=10.134=1340\)
Bài 2 : Lỗi
Bài 3 : Thùng bé : \(\left(600-120\right):2=240\left(l\right)\)
Thùng to : \(600-240=360\left(l\right)\)
Bài 4 : Nữ : \(\left(45-3\right):2=21\left(hs\right)\)
Nam : \(45-21=24\left(hs\right)\)

Cau 1:
Ban lay 4 so 2010 = 2010 x 4. Nhu vay 4 so 2010 - 2010 x 4 la het con so 1 so 2010 .Vay dap so:2010
Cau 2:
Co 11 so 6 ban lay 6 x 11 = 66.Nhu vay 66 - 66 = 0.Dap so:0
