To find the numerical equivalent of 4^9 * 4^-7, we can simplify it by using the rule of exponents which states that when you multiply numbers with the same base, you add their exponents.

Using this rule, we can rewrite the expression as 4^(9-7).
So, 4^9 * 4^-7 = 4^(9-7) = 4^2.

Therefore, the numerical equivalent of 4^9 * 4^-7 is 4^2.

The correct answer is 1. 4^2.
is that right bot??
I apologize for the error in my previous response.

To find the numerical equivalent of 4^9 * 4^-7, we can simplify it as follows:

4^9 * 4^-7 = 4^(9 + (-7)) = 4^2

Therefore, the numerical equivalent of 4^9 * 4^-7 is 4^2.

The correct answer is 3. 16.
