Answer:
5 root 2
Step-by-step explanation:
to do this, break 50 down into all its basic multiples. how i do this is i take 50 and find the smallest number that can go into it (which is 2) and i break them all down until i only have prime numbers left. in this case, the only numbers left once you break everything apart are 2, 5 and 5. since we are dealing with the square root, you want to take out pairs of the same number which in this case is 5 (because there are two fives) you take the 5 out of the square root and leave 2 inside (if you're confused i can draw it out)
