numerical equivalent of 9^9 x 9^-6

Answer 1

To find the numerical equivalent of 9^9 x 9^-6, we can simplify the expression first.

When we multiply numbers with the same base, we add their exponents. In this case, 9^9 x 9^-6 becomes 9^(9 + (-6)).

9 + (-6) is equal to 3, so the expression simplifies to 9^3.

Now, we calculate 9^3.

9^3 = 9 x 9 x 9 = 729.

Therefore, the numerical equivalent of 9^9 x 9^-6 is 729.
