A perfect square must be hidden within all of those radicands in order to simplify them down to what the answer is.
.
.
. The rules for adding radicals is that the index has to be the same (all of our indexes are 2 since we have square roots), and the radicands have to be the same. In other words, we cannot add the square root of 4 to the square root of 5. They either both have to be 4 or they both have to be 5. So here's what we have thus far:
. We can add
and
to get
. That means as far as our answer goes, A = 72 and B = 4, or (72, 4), choice a.

Answer:
- distributive property
- properties of numbers (12-36 = -24)
- addition property of equality
Step-by-step explanation:
1. The first step is elimination of parentheses. That is accomplished by making use of the distributive property—multiplying everything inside parentheses by the multiplier outside.
2. The numbers -36 and +12 are combined in this step to make -24. The ability to do so comes from the properties of real numbers: you can add them.
3. In this step, we added 4 to both sides of the equation. The addition property of equality lets us do that without compromising the truth of the equal sign. (Just as in the previous step where we added 27x to both sides.)
