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:
71 x 71 x 71 x 71 x ... (for a total of 91 times) = 2914135445829898511490495187122177421985567692813925677356128275760513977105763791376066883158370931153491770449116360752266401650092581757028609995676523434547058726871
Therefore, 71 to the power of 91 is 2914135445829898511490495187122177421985567692813925677356128275760513977105763791376066883158370931153491770449116360752266401650092581757028609995676523434547058726871.
