== 数学中的无敌公式（颜金宽原著）:
a n − b n = ( a n m + b n m ) ( a ( m − 1 ) n m + a ( m − 2 ) n m b n m + a ( m − 3 ) n m b 2 n m + a ( m − 4 ) n m b 3 n m + ⋯ + a n m b ( m − 2 ) n m + b ( m − 1 ) n m ) {\displaystyle a^{n}-b^{n}=(a^{\frac {n}{m}}+b^{\frac {n}{m}})(a^{\frac {(m-1)n}{m}}+a^{\frac {(m-2)n}{m}}b^{\frac {n}{m}}+a^{\frac {(m-3)n}{m}}b^{\frac {2n}{m}}+a^{\frac {(m-4)n}{m}}b^{\frac {3n}{m}}+\cdots +a^{\frac {n}{m}}b^{\frac {(m-2)n}{m}}+b^{\frac {(m-1)n}{m}})}
