Find the numerical equivalent of 9^9 • 9^-6

Answer 1

To find the numerical equivalent of 9^9 • 9^-6, we start by applying the rule of exponents, which states that a^m • a^n = a^(m+n). In this case, 9^9 • 9^-6 becomes 9^(9+(-6)), which simplifies to 9^3. Therefore, the numerical equivalent of 9^9 • 9^-6 is 9^3 = 729.
