The expression "x^(1/2)" represents the square root of a number "x." In mathematical terms, it means finding a value that, when multiplied by itself, equals "x." For example, if x is 9, then x^(1/2) equals 3, since 3 * 3 = 9. This operation is fundamental in algebra and is often used in various mathematical calculations. Square roots can be applied in many fields, including geometry, physics, and engineering. They help solve equations, analyze shapes, and understand relationships between different quantities. The square root function is also important in statistics, where it is used to calculate standard deviations and variances.
