\(a,24\times4+24\times3+24\times2\)
\(=24\times\left(4+3+2\right)\)
\(=24\times9\)
\(=216\)
\(b,2007\times16-2007\times14-2007\times2+2007\)
\(=2007\times\left(16-14-2+1\right)\)
\(=2017\times1\)
\(=2017\)
a, 24 x ( 4 + 3 + 2 ) = 24 x 9 = 216
b, 2007 x 16 - 14 - 2 + 1 ) = 2007 x 1 = 2007
a) 24x4+24x3+24x2 b)2007x16-2007x14-2007x2+2007
= 24x(4+3+2) =2007x(16-14-2+1)
=24x9 =2007x1
=216 =2007
a)24x4+24x3+24x2=216
b)2007x16-2007x14-2007x2+2007=2007
Chúc bạn học giỏi nha Edogawa conan!
