Similarly, we can justify the statement discussed in the beginning that if p is a prime number, then p is an irrational number. Irrational numbers are usually expressed in the R/Q form, where the backward slash symbol represents set minus. If it is multiplied twice, then the final product obtained is a rational number. Rest of the verification can be performed by using a free real number calculator. Try the given examples, or type in your own As the given number is in the form of p/q, you can consider it as a rational number. But followers of Pythagoras could not accept the existence of irrational numbers, and it is said that Hippasus was drowned at sea as a punishment from the gods! The symbol P is often used because of the association with the real and rational number. the ratio of two integers. WebSolution: A rational number is any real number that can be written as a fraction whose numerator and denominator are integers (in decimal form, this means a number that is either a terminating or repeating decimal).
