An index number is a number which is raised to a power.

Indices meaning maths. The power also known as the index tells you how many times you have to multiply the number by itself. There are a number of important rules of index numbers. Indices definition a plural of index. In the mathematical process of exponentiation a base number is written alongside a superscript number which is the index or exponent.

Indices the law of indices introduction. Indices are a mathematical concept for expressing very large numbers. The plural of index is indices. Indices show where a number has been multiplied by itself eg squared or cubed or to show roots of numbers eg square root.

Plural indices ˈindisiːz in mathematics the figure which indicates the number of times a figure etc must be multiplied by itself etc. For example 2 5 means that you have to multiply 2 by itself five times 2 2 2 2 2 32. A common convention in computing is to have indices beginning at zero whereas in mathematics indices usually begin at one. For example 27 can be written in index form as 3 3.

Indices explain how many copies of the base number are multiplied. It is written as a small number to the right and above the base number. When a number is expressed with exponents or one number to a power of another it is considered to be in index form. They also present us with many useful properties for manipulating them using what are called the law of indices.

A common question in math will be to write a number in index form using a different number as base. Plural form of index when used in the sense of a key to locate an element in a list vector or matrix in computing or mathematics the subscript numbers after each element are the indices of that element.
