Answer:
2√3
Step-by-step explanation:
Be sure you don't answer √(12) even though the brackets make clear what you mean.
12 factors into 2*2*3
Rule: for ever 2 factors that are the same under a root sign, you can take out 1 of them and throw the other one away.
√(12) = √(2 * 2 * 3) = 2√3.
Notice that the 2 is part of the answer.
