As you can see, we have multiplied the results of each operation by
itself until we got a result that was greater than the value of the
exponent (310). Next, we need to take into consideration the exponent
value 256. This is the penultimate exponent value in the
2n sequence table above and it is less than the
exponent value 310 that we are calculating and it is also less than the
exponent value 512 (which is the exponent value in the2n sequence greater than the value we are
calculating).
This exponent should always fall in the penultimate row. We have no use
for the ultimate row other than the fact that the final row acts as a
place holder. It marks the place where the operation needs to stop but
the final row itself is not involved in any mathematical calculations.
The second step will involve subtracting the penultimate exponent from
the exponent that we are calculating.
