Simplify the radicals.
someone because my book doesnt explain how to do this.

Step-by-step explanation:

For this exercise it is important to remember the following property:

Then, given the expression:

You can follow these steps in order to simplify it:

1. Descompose 216 into its prime factors:

2. The Product of powers property states that:

Then:

3. Now you can substitute:

4. Finally, substituting and simplifying, you get:

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option
