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:
77 x 77 x 77 x 77 x ... (for a total of 68 times) = 191147803442659305966160858400626934785252286572953631954980744119403682339368363190466239658591365925932976481598091710921979281
Therefore, 77 to the power of 68 is 191147803442659305966160858400626934785252286572953631954980744119403682339368363190466239658591365925932976481598091710921979281.
