That is, irrational numbers cannot be expressed as the ratio of two integers. 28. We know that an irrational no has well de A shorthand method of writing very small and very large numbers is called scientific notation, in which we express numbers in terms of exponents of 10. To write a number in scientific notation, move the decimal point to the right of the first digit in the number. Write the digits as a decimal number between 1 and 10.Customarily, the set of irrational numbers is expressed as the set of all real numbers "minus" the set of rational numbers, which can be denoted by either of the following, which are equivalent: R ∖Q R ∖ Q, where the backward slash denotes "set minus".
