Why is the square root of 3 not a rational number?

Since both q and r are odd, we can write q=2m−1 and r=2n−1 for some m,n∈N. … Therefore there exists no rational number r such that r2=3. Hence the root of 3 is an irrational number.

Is 2/3 an irrational number?

In mathematics rational means “ratio like.” So a rational number is one that can be written as the ratio of two integers. For example 3=3/1, −17, and 2/3 are rational numbers. Most real numbers (points on the number-line) are irrational (not rational).

and is therefore rational. Any number which when written as a decimal form which terminates (that is ends with only 0 -value digits following the last digit) or any decimal form number that ends with a sequence which repeats indefinitely is rational.

Is the square root of 8 a rational number?

Take 8 for example. 8 is not prime, correct. But, √8 = √4·√2 = 2·√2. Now the 2 in √2 is prime and therefore the square root of it IS irrational, and an irrational number times a rational number is ALWAYS irrational.
