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:
55 x 55 x 55 x 55 x ... (for a total of 99 times) = 19765429681621893835457042088459510371932765548993434418053761525690539011882682622906981207826785692475389938391234204974146446468462323675652214660658501088619232177734375
Therefore, 55 to the power of 99 is 19765429681621893835457042088459510371932765548993434418053761525690539011882682622906981207826785692475389938391234204974146446468462323675652214660658501088619232177734375.
