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:
25 x 25 x 25 x 25 x ... (for a total of 63 times) = 11754943508222875079687365372222456778186655567720875215087517062784172594547271728515625
Therefore, 25 to the power of 63 is 11754943508222875079687365372222456778186655567720875215087517062784172594547271728515625.
