Answer 2

To solve the expression, let's follow the order of operations (PEMDAS):

1. Parentheses
2. Exponents (Powers)
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

The given expression is: -1 / (-1/3)^2

Step 1: Parentheses First, let's calculate the value inside the parentheses.

-1/3 = -0.333333... (repeating decimal)

Step 2: Exponents (Powers) Next, we square the value inside the parentheses:

(-0.333333...)^2 = 0.111111... (repeating decimal)

Step 3: Division Now, we have -1 divided by 0.111111... (repeating decimal):

-1 ÷ 0.111111... = -9

So, the solution to the expression is -9.
