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:
16 x 16 x 16 x 16 x ... (for a total of 89 times) = 146783911423364576743092537299333564210980159306769991919205685720763064069663027716481187399048043939495936
Therefore, 16 to the power of 89 is 146783911423364576743092537299333564210980159306769991919205685720763064069663027716481187399048043939495936.
