1立方+2立方=9 ,1立方+2立方+3立方=36.1立方+2立方+3立方+.10立方=?

问题描述:

1立方+2立方=9 ,1立方+2立方+3立方=36.1立方+2立方+3立方+.10立方=?
1立方=1,1立方+2立方=9 ,1立方+2立方+3立方=36.1立方+2立方+3立方+.10立方=?1立方=1,1立方+2立方=9 ,1立方+2立方+3立方=36.1立方+2立方+3立方+.N立方=?

1立方+2立方+3立方+.10立方=3025
找规律 规律是1+2=3(1+2)平方方=91立方+2立方=9
1+2+3=6 (1+2+3)平方=36 1立方+2立方+3立方=36
第二个问是
(1+2+3+.+N)平方
