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:
77 x 77 x 77 x 77 x ... (for a total of 99 times) = 5788709987194831926040064230689487964791275816766225861456577194887439652924662418332750963321178418913523800319080816442212796787687881706201273681438984199647603820668204476189223565013
Therefore, 77 to the power of 99 is 5788709987194831926040064230689487964791275816766225861456577194887439652924662418332750963321178418913523800319080816442212796787687881706201273681438984199647603820668204476189223565013.
