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 91 times) = 6089923906954561534081472055814404504998679234627284532262799433927213915929467840055346058357206358944931398081463080893741950785711054613879039802658028961193
Therefore, 57 to the power of 91 is 6089923906954561534081472055814404504998679234627284532262799433927213915929467840055346058357206358944931398081463080893741950785711054613879039802658028961193.
