甚麼是質因數連乘積
Sep 8th 2013, 01:38

質因數連乘積的意思...我不知道該怎麼解釋

我舉個例子:36=2*2*3*3. 12=2*2*3. 58=2*29.

這就是質因數連乘積.

--------------------------------------------------------------------

我想你題目的意思應該是這樣:

圈一個質因數2x2x3x3 ( ) 2x2x3x3( ):

圈2,或是圈3

所以答案為2,3

圈2個質因數2x2x3x3( ) 2x2x3x3( ) 2x2x3x3( ):

圈2跟3,圈2跟2,或圈3跟3

2*3=6,2*2=4,3*3=9

所以答案為4,6,9

圈3個質因數2x2x3x3( ) 2x2x3x3( ):

圈2跟2跟3,或圈2跟3跟3

2*2*3=12,2*3*3=18

所以答案為12,18

圈4個質因數2x2x3x3( )

圈2跟2跟3跟3

2*2*3*3=36

所以答案為36

希望有幫助到你.
