多位数码构成的数字金字塔

Numeral Pyramid with One Digit Number

利用数字1金字塔的结果与符号[b]k的定义,先解决对于任意整数k,[a]_k×[a]_k=?的问题,其中a是多位数码。然后,考虑在任意整数n,m且m≠n的情形下[a]_n×[a]_m=?的问题,讨论了解的结构。同时,给出几个例子加以说明。

According to the result of the number 1 pyramid and the definition of the symbol [ b ] k,Firstly,the question [ a ] k×[ a ] k=？ may be solved for arbitrary integer number k ,where a is multi-digit number.Then the question [ a] n ×[ a] m =？ may be solved for arbitrary integer number n and m in the case of m≠n .The structure of the solution may be discussed.Meanwhile,some examples may be given for reference.
