A [http://mathworld.wolfram.com/NarcissisticNumber.html Narcissistic decimal number] is a positive decimal number, <math>n</math> in which if there are <math>m</math> digits in the number then the sum of all the individual digits of the number raised to the power <math>m</math> is equal to <math>n</math>. |
||
For example, if <math>n</math> is 153 then <math>m</math>, the number of digits is 3 and we have <math>1^3+5^3+3^3 = 1+125+27 = 153</math> and so 153 is a narcissistic decimal number. |
