\(15\cdot12-3\cdot5\cdot10\)
\(C1:=180-15\cdot10\)
\(=180-150\)
\(=30\)
\(C2:=15\cdot12-15\cdot10\)
\(=15\cdot\left(12-10\right)\)
\(=15\cdot2\)
\(=30\)
c1:(15.12)-(3.5.10)
=180-150=30
c2 đang nghĩ
c1 : 15 . 12 - 3.5.10
= 180 - 150
= 30
c2 : 15 . 12 - 3 . 5 . 10
= 15 . 12 - 15 . 10
= 15 . ( 12 - 10 )
= 15 . 2
= 30
hok tốt
C1:\(15.12-3.5.10\)
\(=180-150\)
\(=30\)
C2:\(15.12-3\cdot5\cdot10\)
\(=15\cdot12-15\cdot10\)
\(=15\cdot\left(12-10\right)\)
\(=15\cdot2\)
\(=30\)
Chúc bạn học tốt
