Top Answer

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 notbe expressed as a ratio.

Not necessarily. The sum of two irrational numbers can be rational or irrational.

You can not add irrational numbers. You can round off irrational numbers and then add them but in the process of rounding off the numbers, you make them rational. Then the sum becomes rational.

Rational and Irrational Numbers

Yes. The sum of two irrational numbers can be rational, or irrational.

Yes, you can.

no

no

No, you can't.

Sure; for example, 10 + pi is irrational, 10 - pi is irrational. Both are positive. If you add them, you get 20.

no

Yes. sqrt(2) + sqrt(2) = 2*sqrt(2), an irrational number.

Yes. Consider 4+sqrt(2), and 3-sqrt(2). Both are irrational numbers. Their sum is 7.

No, the result is always an irrational number. In more advanced math it is possible to add an infinite amount of rational numbers by way of Taylor Series and get an irrational number. This is how numbers like "Pi" and "e" are derived.

yes

Irrational numbers are not closed under any of the fundamental operations. You can always find cases where you add two irrational numbers (for example), and get a rational result. On the other hand, the set of real numbers (which includes both rational and irrational numbers) is closed under addition, subtraction, and multiplication - and if you exclude the zero, under division.

They are irrational numbers!

Irrational numbers are real numbers.

No. The set of rational numbers is closed under addition (and multiplication).

yes * * * * * No. Rational and irrational numbers are two DISJOINT subsets of the real numbers. That is, no rational number is irrational and no irrational is rational.

No. Some negative numbers are irrational and some are not. Some irrational numbers are negative and some are not.

Numbers that can't be expressed as fractions are irrational

properties of irrational numbers

All irrational numbers are real, but not all real numbers are irrational.

Yes, no irrational numbers are whole numbers.
