To find the numerical equivalent of 4^9 • 4^(-7), we can use the property of exponents that states that when you multiply two numbers with the same base, you keep the base and add the exponents.
Therefore, 4^9 • 4^(-7) can be simplified to 4^(9 + -7).
When you add the exponents, you get 4^2.
Thus, the numerical equivalent of 4^9 • 4^(-7) is 4^2, which equals 16.
