The first step a math tutor would suggest 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 90 times) = 10079534913798375595334428492639690182987886988234765259376172137690670928443160519194747221507973813150355011579433388142725699024479577496012835469728180765164976937866625024
Therefore, 88 to the power of 90 is 10079534913798375595334428492639690182987886988234765259376172137690670928443160519194747221507973813150355011579433388142725699024479577496012835469728180765164976937866625024.
