By using the Fundamental Theorem of Arithmetic form, the positive integer can be expressed in the form of the product of its prime number as: a = p1 p2 p3.. pn ..(1) Where, p1, p2, p3, , pn define all the prime factors of a. a^2 = ( p1 p2 p3.. pn) ( p1 p2 p3.. pn), a^2 = (p1)^2 (p2)^2 (p3 )^2.. (pn)2. To solve a rational expression start by simplifying the expression by finding a common factor in the numerator and denominator and canceling it out. WebRational number and irrational number can be represented on a number line. Simply in other words, we can say that irrational numbers cannot be explained as the quotient of two integers. For example, by truncating the decimal expansion of 2, show that 2 is between 1 and 2, then between 1.4 and 1.5, and explain how to continue on to get better approximations.
