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:
59 x 59 x 59 x 59 x ... (for a total of 90 times) = 2380570501477418455536417027163726132841735238003286589912670017275165059229542279513494916045620298944774332353856719678676325338439450871477329204370784332601
Therefore, 59 to the power of 90 is 2380570501477418455536417027163726132841735238003286589912670017275165059229542279513494916045620298944774332353856719678676325338439450871477329204370784332601.
