1、10=1*4+2*3
11=1*3+2*4
所以?=1*2+3*4=14
2、3*8=4*6=1+2+5+7+9

、10=1*4+2*3
11=1*3+2*4
所以?=1*2+3*4=14
2、3*8=4*6=1+2+5+7+9追问 谢谢大师!

还有最后一题:
Find the regularity(规律)of the equality:a#b=(a×b)/(a-b).a#b=3,a=________,b=_______回答 a=6,b=2需要过程吗追问 嗯嗯。十分感谢!!!回答 a#b=3等价于ab=3(a-b)
等价于(3-b)(a+3)=9。
由于a,b为正整数(题目可能漏了此条件)
且a+3>0,所以3-b>0。
所以3-b=1,a+3=9。
