Next we can simplify 18 using what we already know about simplifying radicals. The work is shown below. − 18 = i 18 For a > 0 , − a = i a = i ⋅ 9 ⋅ 2 9 is a perfect square factor of 18 = i 9 ⋅ 2 a b = a ⋅ b when a, b ≥ 0 = i ⋅ 3 ⋅ 2 9 = 3 = 3 i 2 Multiplication is commutative. So it follows that − 18 = 3 i 2 .

After discovering irrational numbers like $\sqrt{2}$, it becomes natural to wonder if there are any numbers which aren't a root of any polynomial with rational coefficients. So at that point we have already discovered the idea of transcendental numbers but we don't know if any exist, so it's a nice puzzle.The set of irrational numbers is the set of numbers that are not rational, are nonrepeating, and are nonterminating: [latex]\{h|h\text{ is not a rational number}\}[/latex]. ... We have already seen some real number examples of exponential notation, a shorthand method of writing products of the same factor. ...0 n. Irrational Numbers: the collection of all decimal numbers that neither terminate. nor repeat. The collection of real numbers which are not rational. Real Numbers: the collection of all rational and irrational numbers. A set is a collection of objects. We often call these objects ____________, } 7, 3, 2 { −=A. , the set of irrational numbers,It has an infinite number of non-recurring decimals. Therefore, surds are irrational numbers. There are certain rules that we follow to simplify an expression involving surds. Rationalising the denominator is one way to simplify these expressions. It is done by eliminating the surd in the denominator. This is shown in Rules 3, 5 and 6.You can think of the real numbers as every possible decimal number. This includes all the rational numbers—i.e., 4, 3/5, 0.6783, and -86 are all decimal numbers. If we include all the irrational numbers, we can represent them with decimals that never terminate.
