Square Roots

A square root is a number that, when multiplied by itself, gives a specified number. For example, the square root of 16 is 4, since 4 x 4 = 16. Square roots are often represented with the radical symbol (√). In general, every positive number has two square roots: one positive and one negative. Square roots are useful in various fields, including mathematics, science, and engineering, as they help solve equations and understand relationships between numbers. They also appear in real-world applications, such as calculating areas and understanding geometric shapes.
