To find the numerical equivalent of 9^9 * 9^-6, we need to simplify the expression first.
Applying the rules of exponents, we can rewrite 9^9 * 9^-6 as (9^9 / 9^6) because when two exponents have the same base, we can subtract the exponents when dividing.
Now, let's simplify the expression:
9^9 / 9^6 = 9^(9-6) = 9^3
Calculating 9^3:
9^3 = 9 * 9 * 9 = 729
Therefore, the numerical equivalent of 9^9 * 9^-6 is 729.
