Find the numerical equivalent of 4^(9) . 4^(-7)
4^(2)
4^(16)
4
16
To find the numerical equivalent of the given expression, we can use the property of exponents which states that when multiplying two numbers with the same base, we add their exponents.
Therefore, 4^9 * 4^(-7) is equal to 4^(9 + (-7)). Simplifying the exponent, we get 4^2.
4^2 is equal to 16.
So, the numerical equivalent of 4^9 * 4^(-7) is 16 (Option D).
