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:
72 x 72 x 72 x 72 x ... (for a total of 84 times) = 1037360483429611165628236060598206833885494848584979754325623976873986064455858573437411208815841589250848858164512381409584162942053834671749595421481107456
Therefore, 72 to the power of 84 is 1037360483429611165628236060598206833885494848584979754325623976873986064455858573437411208815841589250848858164512381409584162942053834671749595421481107456.
