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:
58 x 58 x 58 x 58 x ... (for a total of 85 times) = 778716636120475217235294996332936046734099891222280347589967911434638443150066222107625919216282934217683098445463421924094897030113233403382195027968
Therefore, 58 to the power of 85 is 778716636120475217235294996332936046734099891222280347589967911434638443150066222107625919216282934217683098445463421924094897030113233403382195027968.
