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:
86 x 86 x 86 x 86 x ... (for a total of 89 times) = 14803423396265347641394761085877648907222307241268803585159590269975316801050068158328039068697405228055970604731302309932812151078533738506052124917240870339530605163708416
Therefore, 86 to the power of 89 is 14803423396265347641394761085877648907222307241268803585159590269975316801050068158328039068697405228055970604731302309932812151078533738506052124917240870339530605163708416.
