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 \( 4 \times 4 = 16 \).
