Answer:
√4 = 2
Because 2 × 2 = 4
If you want to get square root of any number find the number which you can multiply two times to give you that certain number
Since you subtract 16 from the y value, P is (-2, 6), and the y value comes second (meaning that it's 6), we get 6-16=-10
The answer you are looking for is B, there is a small chance of the event occurring. <span />
2 sqrt3 + 3 sqrt3
= 5 sqrt3
Since this contains the irrational sqrt3 it is irrational
