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:
91 x 91 x 91 x 91 x ... (for a total of 74 times) = 9312430225411293786067539891809411182372516719347494729507459644036403410431434948395050930043267508375907952537567287802393563656372767280040761
Therefore, 91 to the power of 74 is 9312430225411293786067539891809411182372516719347494729507459644036403410431434948395050930043267508375907952537567287802393563656372767280040761.
