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:
75 x 75 x 75 x 75 x ... (for a total of 86 times) = 179998402899345680533965480499857407308559999910322021491274126491493963296199735967679482473768286766361795290600973673024454146940342980087734758853912353515625
Therefore, 75 to the power of 86 is 179998402899345680533965480499857407308559999910322021491274126491493963296199735967679482473768286766361795290600973673024454146940342980087734758853912353515625.
