Answer:
1) 9/49
Explanation:
Let's start with the original equation,
7^-2 * (-3)^2
First, we'll solve for the individual parts. Remember that the negative exponent rule is x^-2 -> 1/x^2
1/49 * 9
This is equivalent to 1/49 * 9/1 which is 9/49
9/49
This cannot be simplified any further so your final answer is 9/49
