Exponent
   0            1
   1           1 1
   2          1 2 1
   3         1 3 3 1
   4        1 4 6 4 1
   5       1 5 10 10 5 1

You might notice that the exponent is the second number in each row (and zero if there is no second number in the row). This pattern might be a way you could remember how this works.
