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:
28 x 28 x 28 x 28 x ... (for a total of 98 times) = 6629596118084252223273542208824283657290268776403263605045647117020330299074915482786099275940697120359897868327699108913504049887463933476864
Therefore, 28 to the power of 98 is 6629596118084252223273542208824283657290268776403263605045647117020330299074915482786099275940697120359897868327699108913504049887463933476864.
