The square root of 3 is an irrational number
2/15 is the ratio of 2 to 15 ... precisely the definition of a rational number.
The square root of 3 is an irrational number
There are an infinite number of irrational numbers between 2 and 4. See the link below for the definition of irrational numbers. The two most popular irrational numbers between 2 and 4 are pi (3.14159...) and e (2.71828...).
e
- 2/15 is the ratio of -2 and 15, or of 2 and -15 ... nice and rational.
Find the difference between the two numbers, then add an irrational number between zero and one, divided by this difference, to the lower number. Such an irrational number might be pi/10, (square root of 2) / 2, etc.
There are infinitely many irrational numbers between sqrt(2) and sqrt(3).
(root 2)/3
I can't tell you the irrational number between 0.2 and 0.3; there an infinite number of irrationals in this range.For an example - root(2) / 7 is slightly more than 0.202, and is irrational.
Sometimes. eg the irrational number √2 squared is 2 which is rational (2 = 2/1) eg the irrational number √(√2) squared is √2 which is irrational.
The product of two irrational numbers may be rational or irrational. For example, sqrt(2) is irrational, and sqrt(2)*sqrt(2) = 2, a rational number. On the other hand, (2^(1/4)) * (2^(1/4)) = 2^(1/2) = sqrt(2), so here two irrational numbers multiply to give an irrational number.
