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:
53 x 53 x 53 x 53 x ... (for a total of 99 times) = 505022922159645983659900991254016013358935626661576711807796957540547778933217118190595565737362669368974102907580526513744714818233383354719457094408800189681698987848717
Therefore, 53 to the power of 99 is 505022922159645983659900991254016013358935626661576711807796957540547778933217118190595565737362669368974102907580526513744714818233383354719457094408800189681698987848717.
