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 98 times) = 99568244445778267314305024860481987849444034699538674129617865836635181344566135058943117170011417871311465432881959713995456695556640625
Therefore, 25 to the power of 98 is 99568244445778267314305024860481987849444034699538674129617865836635181344566135058943117170011417871311465432881959713995456695556640625.
