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:
63 x 63 x 63 x 63 x ... (for a total of 91 times) = 54952822070621314414990714070408968038125761295064166224742225593903510803919614201281057230826037012835134324161148593572667939222962565741886302789432865874781887
Therefore, 63 to the power of 91 is 54952822070621314414990714070408968038125761295064166224742225593903510803919614201281057230826037012835134324161148593572667939222962565741886302789432865874781887.
