The first step 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:
15 x 15 x 15 x 15 x ... (for a total of 88 times) = 31335079212635863856557128302005353076984064082941051048101220068142769292762750410474836826324462890625
Therefore, 15 to the power of 88 is 31335079212635863856557128302005353076984064082941051048101220068142769292762750410474836826324462890625.
