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:
83 x 83 x 83 x 83 x ... (for a total of 86 times) = 1098287256145075980347536143190913905055679060084990674812431249364793626029566931419017072943965116293710964497444697093541617595430106085533232289604200474123318969
Therefore, 83 to the power of 86 is 1098287256145075980347536143190913905055679060084990674812431249364793626029566931419017072943965116293710964497444697093541617595430106085533232289604200474123318969.
