The square root of 1349 is the same as the square root of 13 over the square root of 49 point. So you can just take the square over the top and divide it by the square to the bottom. Whenever you have a square root equation and the square of 13 is irrational, so it stays the square of 13 point. The square of 49 is 7, so really a square of 13 over 7.
