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:
43 x 43 x 43 x 43 x ... (for a total of 85 times) = 6995499409462986574422921040970773084402338410477762239058637578397214686965707059210832883784261949625683609201418241231394157789530376443
Therefore, 43 to the power of 85 is 6995499409462986574422921040970773084402338410477762239058637578397214686965707059210832883784261949625683609201418241231394157789530376443.
