First you need to set your denominators equally to their lowest common. Then you take that lowest common and use it with the two or more irrationals. Using it, you need to multiply the denominator of the irrationals to get the LCD, you multiply both the top and bottom. The bootoms will all be the same but the tops wont. Then add the tops together and reduce. The denominator will be the LCD!

Ans 2. The answer above fundamentally misunderstands what an irrational number is. In order to have a numerator and a denominator, you must be able to express your number as a ratio. The word irrational means that this is a number that can not be expressed as a ratio.
