How do you simplify square roots that are irrational?
Guess what the square root of the irrational number is. For example, if your irrational number is 2, you might guess 1.2.
Divide the initial irrational number by the guessed number. For example, 2 divided by 1.2 is 1.67.
Add the resulting sum to the original guessed number. For example, 1.67 plus 1.2 is 2.87.
Divide the new result by 2. In our example, 2.87 divided by 2 is 1.435.
