The first step 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:
75 x 75 x 75 x 75 x ... (for a total of 99 times) = 427626958050867175200512180875203253615506447459793591901708601668921306795309560965297602915802115592667812933172011597897658957410407723549630558401712931981819565407931804656982421875
Therefore, 75 to the power of 99 is 427626958050867175200512180875203253615506447459793591901708601668921306795309560965297602915802115592667812933172011597897658957410407723549630558401712931981819565407931804656982421875.
