Find the numerical equivalent of 4^9 * 4^-7
1. 4^2
2. 4
3. 16
4. 4^16
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.
To find the numerical equivalent of 4^9 * 4^-7, we can simplify the expression first.
Remember that when you multiply numbers with the same base, you add their exponents. So we have:
4^9 * 4^-7 = 4^(9 + (-7))
Now, when you add a positive exponent with a negative exponent, the result is actually division with the base. Therefore, we have:
4^(9 + (-7)) = 4^2
This equals 16.
So the numerical equivalent of 4^9 * 4^-7 is option 3: 16.
To find the numerical equivalent of 4^9 * 4^-7, we can use the rules of exponents.
First, we know that when multiplying two numbers with the same base, we add their exponents. So, 4^9 * 4^-7 becomes 4^(9 + (-7)).
Next, we simplify the exponent. 9 + (-7) is equal to 2.
Therefore, 4^9 * 4^-7 is equivalent to 4^2.
The answer is 16.
So, the correct choice is 3. 16.
