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:
57 x 57 x 57 x 57 x ... (for a total of 90 times) = 106840770297448447966341615014287798333310162011004991794084200595214279226832769123778001023810637876226866633008124226205999136591422010769807715836105771249
Therefore, 57 to the power of 90 is 106840770297448447966341615014287798333310162011004991794084200595214279226832769123778001023810637876226866633008124226205999136591422010769807715836105771249.
