18 * 7 + 18 * 16 - 18 * 14 + 18
= 18 * (7 + 16 - 14 + 1)
= 18 * 8
= 144
\(18\times7+18\times16-18\times14+18\)
\(=18\times\left(7+16-14+1\right)\)
\(=18\times10\)
\(=180\)
18 x 7 + 18 x 16 - 18 x 14 + 18
= 18 x ( 7 + 16 - 14 +1 )
= 18 x ( 23 -14 +1 )
= 18 x ( 9 +1 )
= 18 x 10
= 180
18 * 7 + 18 * 16 - 18 * 14 + 18
= 18 * (7 + 16 - 14 + 1)
= 18 * 10
= 180
k cho mk nha mọi người
\(18\times7+18\times16-18\times14+18\)
\(=18\times\left(7+16-14+1\right)\)
\(=18\times10\)
\(=180\)
_Chúc bạn học tốt_
\(18\times7+18\times16-18\times14+18\)
\(=18\times7+18\times16-18\times14+18\times1\)
\(=18\times\left(7+16-14+1\right)\)
\(=18\times10\)
\(=180\)

Trả lời:
\(18\cdot7+18\cdot16-18\cdot14+18\)
\(=18\cdot\left(7+16-14+1\right)\)
\(=18\cdot10\)
\(=180\)
