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 87 times) = 387192725719135508348407853146159504334093181244646523342530498120261550586020300818366858868095241504700834612187917336364469649795709683561192991876980395737088
Therefore, 72 to the power of 87 is 387192725719135508348407853146159504334093181244646523342530498120261550586020300818366858868095241504700834612187917336364469649795709683561192991876980395737088.
