hatványkitevi

Hatványkitevi, often translated as exponent or power, is a fundamental concept in mathematics. It represents repeated multiplication of a base number by itself. The general form is written as a^n, where 'a' is the base and 'n' is the exponent. The exponent 'n' indicates how many times the base 'a' is multiplied by itself. For instance, 2^3 means 2 multiplied by itself three times, resulting in 2 * 2 * 2 = 8.

The exponent can be a positive integer, a negative integer, zero, or even a fraction or irrational number, each with specific rules for calculation. A positive integer exponent, as in the example above, signifies straightforward repeated multiplication. A zero exponent, regardless of the base (except for 0^0, which is often considered indeterminate), always results in 1 (e.g., 5^0 = 1). A negative exponent indicates the reciprocal of the base raised to the positive version of the exponent (e.g., 2^-3 = 1/2^3 = 1/8). Fractional exponents represent roots, such as x^(1/n) being the nth root of x.

Understanding hatványkitevi is crucial for various mathematical operations, including algebra, calculus, and scientific calculations. It simplifies expressions, describes growth and decay patterns, and forms the basis for logarithms.
