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:
89 x 89 x 89 x 89 x ... (for a total of 68 times) = 3618432303012102779589971430537360612943045177483511284403558587181496130688080059994656134793952569789305311411246905863713600531681
Therefore, 89 to the power of 68 is 3618432303012102779589971430537360612943045177483511284403558587181496130688080059994656134793952569789305311411246905863713600531681.
