Find the numerical equivalent 3^9 . 3^-5
To find the numerical equivalent of 3^9 * 3^-5, we can simplify the expression.
First, we simplify the exponents by using the exponent rule that says a^m * a^n = a^(m+n).
So, 3^9 * 3^-5 can be written as 3^(9 + (-5)).
Simplifying further, 3^(9 + (-5)) is equal to 3^4.
To find the numerical equivalent of 3^4, we multiply 3 by itself 4 times.
3 * 3 * 3 * 3 = 81.
Therefore, the numerical equivalent of 3^9 * 3^-5 is 81.
