c1 :27x6-27x4
= 162 - 108
=54
c2 : 27x6-27x4
=27 x ( 6-4)
= 27 x2
=54
C1:27x6-27x4 C2:27x6-27x4
=27x(6-4) =162-108
=27x2 =54
=54
Cách 1 : \(27\times6-27\times4\)
\(=162-108\)
\(=54\)
Cách 2 : \(27\times6-27\times4\)
\(=27\times\left(6-4\right)\)
\(=27\times2\)
\(=54\)
27*6-27*4
c1:= 27*(6-4)
=27*2
=54
c2:=162-108
=54
nếu đúng bạn tích nha
C1 : 27 x 6 - 27 x 4
= 27 x (6 - 4)
= 27 x 2
= 54
C2 : 27 x 6 - 27 x 4
= 162 - 108
= 54
