1个3相乘各位是3,2个3相乘各位是9,3个3相乘各位是7,4个3相乘各位是1...
如此循环可发现其个位数为3.9.7.1循环.
1个4相乘各位是4,2个4相乘各位是6,3个4相乘各位是4,4个4相乘各位是6...
如此循环可发现其个位数为4.6循环.
所以85（=21×4+1）个3相乘各位是3,80（=40×2）个4相乘各位是6
所以答案的各位是3+6=9.

3x3x3x3x3x3x3········x3共85个3相乘，加上4x4x4x4x4x4····共80个4相乘，他们的和是575

3

3:3
3*3=9:9
3*3*3=27:7
3*3*3*3=81:1
3*3*3*3*3=243:3
......
所以3是3971，3971...
所以85除以3=28余1所以个位为3
4也和上面一样是46，46，....
所以80除以2等于40所以各位为6
所以他们和的个位为3+6=9！
