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:
28 x 28 x 28 x 28 x ... (for a total of 63 times) = 14823678064620009560967982583709696642081067164215936192390141374448196339375985169218404352
Therefore, 28 to the power of 63 is 14823678064620009560967982583709696642081067164215936192390141374448196339375985169218404352.
