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:
88 x 88 x 88 x 88 x ... (for a total of 91 times) = 886999072414257052389429707352292736102934054964659342825103148116779041702998125689137755492701695557231241018990138156559861514154202819649129521336079907334517970532263002112
Therefore, 88 to the power of 91 is 886999072414257052389429707352292736102934054964659342825103148116779041702998125689137755492701695557231241018990138156559861514154202819649129521336079907334517970532263002112.
