Find the numerical equivalent of 3 ^ 9 * 3 ^ - 5 (1 point)
To find the numerical equivalent of 3^9 * 3^(-5), we can use the rule of exponents that states when multiplying exponents with the same base, you add the exponents.
So, 3^9 * 3^(-5) can be simplified as 3^(9 + (-5)) = 3^4.
Therefore, the numerical equivalent of 3^9 * 3^(-5) is 81.
To find the numerical equivalent of the expression 3^9 * 3^-5, we can simplify it step by step.
Step 1: Simplify the exponents using the product rule of exponents.
- 3^9 * 3^-5 = 3^(9 + -5) = 3^4
Step 2: Evaluate 3^4.
- 3^4 = 3 * 3 * 3 * 3 = 81
Therefore, the numerical equivalent of 3^9 * 3^-5 is 81.
