enter your answer in simplest radical form, in the box.

Step-by-step explanation:

For this exercise it is important to remember the following:

Given the following expression:

You can notice that the radicand (the number inside the square root) is negative. Therefore, in order to simplify the expression, you need to follow these steps:

2. Descompose 12 into its prime factors:

3. Substitute into the expression:

4. Since , you can simplify it:

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.

the answer is 99.
