Answer 4

It is possible to simplify 50 as represented in a square root. Factoring 50, we get:

2 * 5 * 5

All of these are prime numbers. We've factored 50 as far as it will go. You might notice that there are two fives in 50. What happens if we multiply those two fives together? We get 25 as a result of that and 25 so happens to be a perfect square. You can take perfect squares out of the square root symbol.

Similarly, find for 2 and add it up..!
