The first step is to understand what it means when a number has an exponent. The “power” of a number indicates how many times the base would be multiplied by itself to reach the correct value.
The second step is to write the number in the base-exponent form, and lastly calculate what the final result would be. Consider the example of 2 to the power of 4: in exponent form that would be
So re-applying these steps to our particular problem, we first convert our word problem to a base-exponent form of:
To simplify this, all that is needed is to multiply it out:
22 x 22 x 22 x 22 x ... (for a total of 99 times) = 7940455229131020726743381854098636404416494857253597834213839631812461973959829138671244625892339275269942476459642840306880094404608
Therefore, 22 to the power of 99 is 7940455229131020726743381854098636404416494857253597834213839631812461973959829138671244625892339275269942476459642840306880094404608.
