Is–9anirrationalnumber?
Solution
No, -9 is not an irrational number. Here's why:
- An irrational number is a number that cannot be expressed as a simple fraction.
- It means it cannot be written as a ratio, such as p/q, where p and q are integers, q ≠ 0.
- However, -9 can be expressed as a simple fraction, -9/1, where both -9 and 1 are integers.
- Therefore, -9 is not an irrational number. It is an integer and a rational number.

The numbering system which uses base-8 is called octal system. A base (also called radix) is the number of unique digits or symbols (including 0) that are used to represent a given number.In octal system (or the base-8 system), a total of 8 digits (0, 1, 2, 3, 4, 5, 6 and 7) are used to represent a number of any size (magnitude).For example, Zero is represented as 0, where0 = (0 * 80) = (0 * 1)Similarly the numbers 1 One (1), 2 and 7 are represented as follows: :1 = (1 * 80) = (1 * 1)2 = (2 * 80) = (2 * 1)...7 = (7 * 80) = (7 * 1)Now, let us try to represent the following numbers in octal system:Eighteen (18): Since 0 to 7 are the only digits that can be used to represent 18, let us divide 18 by 8 and write the quotient and remainder as follows:[quotient][remainder], i.e.: [2][2]18 = (2 * 81) + (2 * 80) = (16) + (2)Four Hundred and Twenty One (421): Since 0 to 7 are the only digits that can be used to represent 421,, let us divide it by 8 and write the quotient and remainder as follows:[quotient][remainder], i.e.: [52] [5] (further dividing 52 by 8 we get [6][4]), which is [6][4][5]421 = (6 * 82) + (4 * 81) + (5 * 80) = (384) + (32) + (5)Click on Live Demo to understand the conversion of decimal number system to octal number system.In order to differentiate from decimal numbers, octal numerals are prefixed with a leading 0 (zero).For example, to store an octal value of seven into a variable number_seven, we writeint number_seven = 07;Similarly, if we want to store an octal representation of a decimal number 9 in a variable number_nine, we writeint number_nine = 011;Click on Live Demo to understand the conversion of octal number system to decimal number system.Select all the correct statements from the given statements.In octal system, the base is 10.In octal system, decimal value of 20 is represented as 21In octal system, decimal 8 is represented as 10In octal system, decimal of 10 is written as 012
