Irrational numbers and examples
WebA number that cannot be expressed that way is irrational. For example, one third in decimal form is 0.33333333333333 (the threes go on forever). However, one third can be express as 1 divided by 3, and since 1 and 3 are both integers, one third is a rational number. WebSo, if a² = 7.29. Then, a = 7.29. = 7.29 100. = 27 10. a = 27 10, from the definition of irrational numbers we know that, a number is irrational if it cannot be written in the form of p q, where p and q are integers. Here 27 10 is of the form p q where both 27 and 10 are integers. Hence, 27 10 is a rational number.
