Pi = 3.14... (or π) is a mathematical constant representing the ratio of a circle's circumference to its diameter. It is an irrational number, meaning that it cannot be expressed as the ratio of two integers.
An irrational number is any real number that cannot be expressed as a fraction or ratio of two integers. They have decimal representations that neither terminate nor repeat.
In mathematics, a radical is a mathematical symbol (√) used to denote the square root or any other non-integer-root operation. It is used to indicate the principal square root or the positive square root of a number.
The radicand is the number or expression inside the radical symbol (√). It represents the value for which we need to find the square root or any other non-integer root. For example, in the expression √9, the radicand is 9.
