The square root of a number is a value that, when multiplied by itself, gives the original number. In mathematical terms, if \\( x \\) is the square root of \\( y \\), then: \\\[ x^2 = y \\\] For example: - The square root of 9 is 3, since \\( 3 \\times 3 = 9 \\). - The square root of 16 is 4, since \\( 4 \\times 4 = 16 \\).
