Exponentiation is an operation involving two numbers: the base and the exponent or power. The exponent is usually shown as a superscript to the right of the base, and it indicates how many times the base is multiplied by itself.
Learn how to write numbers in scientific notation, a way of expressing large or small numbers as m × 10 n, where n is an integer and m is a nonzero real number. Find out the history, advantages, and applications of scientific notation in science, math, and engineering.
Learn about the exponential function, a mathematical function that relates the rate of change to the value of the function. See how it is defined, graphed, and extended to complex numbers and matrices, and how it relates to logarithms and trigonometric functions.
The Hurst exponent measures the long-term memory of time series and relates to fractal dimension and autocorrelation. Learn how it is calculated, how it varies for different types of processes, and how it is used in hydrology, economics, biology and more.
Learn how to compute large powers of a number or an element of a semigroup using squaring and multiplication. Compare different methods, such as binary exponentiation, 2k-ary method, sliding-window method, Montgomery's ladder and fixed-base exponent.
