For example, the square roots that are not perfect will always result in an irrational number. and a rational is going to be irrational. From the theorem stated above, if 2 is a prime factor of p2, then 2 is also a prime factor of p. Substituting this value of p in equation (3), we have. 4/1 * 10/10 = 40/10 I would say that it is 3.2468. complex analysis. When we can't simplify a number to remove a square root (or cube root etc) then it is a surd. 75 How can we represent that as Solution: Since the decimal expansion of a rational number either terminates or repeats. 5,2 1/4,4,0.25555, 13/5 ,4,3 -5 , -2 1/4 , 4 0.25555 , 13/5 , 4 , 3 Whole Number: Integer: Rational Number: Irrational Number: Real Number: The following theorem is used to prove the above statement. A rational expression is called a "rational" expression because it can be written as a fraction, with the polynomial expression in the numerator and the polynomial expression in the denominator. We know that is also an irrational number, but if is multiplied by , the result is 2, which is also an irrational number.
