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 77 times) = 291089991465885207157110469823613808301508452017686087349124177032138857687247167996791522348031139
Therefore, 19 to the power of 77 is 291089991465885207157110469823613808301508452017686087349124177032138857687247167996791522348031139.
