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:
19 x 19 x 19 x 19 x ... (for a total of 89 times) = 644273820902285213467612610982425326202134820226376369682495831833935480875425331931243980427454954135330829187379
Therefore, 19 to the power of 89 is 644273820902285213467612610982425326202134820226376369682495831833935480875425331931243980427454954135330829187379.
