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:
57 x 57 x 57 x 57 x ... (for a total of 86 times) = 10121330065945280600706803174259627138469403518529885682474281746962157281610031026311763424786587067984065806076384819043309974732990458296641665327249
Therefore, 57 to the power of 86 is 10121330065945280600706803174259627138469403518529885682474281746962157281610031026311763424786587067984065806076384819043309974732990458296641665327249.
