【題目】奇數(shù)個奇數(shù)相加得奇數(shù),偶數(shù)個奇數(shù)相加得奇數(shù),奇數(shù)乘奇數(shù)得奇數(shù),幾個乘數(shù)中,只要有一個偶數(shù),積一定是偶數(shù). .(判斷對錯)
【答案】×
【解析】
試題分析:根據(jù)偶數(shù)+偶數(shù)=偶數(shù);奇數(shù)+奇數(shù)=偶數(shù),偶數(shù)+奇數(shù)=奇數(shù),偶數(shù)×奇數(shù)=偶數(shù),奇數(shù)×奇數(shù)=奇數(shù),據(jù)此解答即可.
解:根據(jù)偶數(shù)+偶數(shù)=偶數(shù);奇數(shù)+奇數(shù)=偶數(shù),偶數(shù)+奇數(shù)=奇數(shù),偶數(shù)×奇數(shù)=偶數(shù),奇數(shù)×奇數(shù)=奇數(shù),
所以奇數(shù)個奇數(shù)相加得奇數(shù),偶數(shù)個奇數(shù)相加得偶數(shù),奇數(shù)乘奇數(shù)得奇數(shù),所以幾個乘數(shù)中,只要有一個偶數(shù),積一定是偶數(shù).
所以奇數(shù)個奇數(shù)相加得奇數(shù),偶數(shù)個奇數(shù)相加得奇數(shù),奇數(shù)乘奇數(shù)得奇數(shù),幾個乘數(shù)中,只要有一個偶數(shù),積一定是偶數(shù)說法錯誤.
故答案為:×.
