提问:

我觉得这题答案应该是A吧?∵105拆分质因数可得105=3*5*7(3个完全不同的质因数)∴x+y+z=15。怎么会是C呢????

提问:

想向May老师提问。这题我知道条件1单独成立,但对条件2没什么思路,只能想到穷举法,当p等于2*5,3*5,3*5,2*3,2*5,3*5时,m等于2*3,2*3,2*5,5,3,2,然后一个个除发现有的余数是1,有的余数大于1,条件2单独不成立。想问老师这个思路对吗?有没有更加简洁的思路?

提问:

第8题的思路是以BC为底,从F向BC做垂线,跟BC交点H,FH为三角形FBC的高。然后三角形BFH跟三角形BDC相似,h:30=BF:BD,但是BF长度未知,望老师解答。
