## Index numbers maths

Indices & the Law of Indices Introduction. Indices are a useful way of more simply expressing large numbers. They also present us with many useful properties for manipulating them using what are called the Law of Indices. What are Indices? The expression 2 5 is defined as follows: We call "2" the base and "5" the index. Law of Indices Indices are a mathematical concept for expressing very large numbers. They are also known as powers or exponents. In the mathematical process of exponentiation, a base number is written alongside a superscript number, which is the index or exponent. Indices explain how many copies of the base number are multiplied.

The index of a number says how many times to use the number in a multiplication. It is written as a small number to the right and above the base number. In this example: 8 2 = 8 × 8 = 64 The plural of index is indices. (Other names for index are exponent or power.) Index Number. A statistic which assigns a single number to several individual statistics in order to quantify trends. The best-known index in the United States is the consumer price index, which gives a sort of "average" value for inflation based on price changes for a group of selected products. When a number is expressed with exponents, or one number to a power of another, it is considered to be in index form. For example, 27 can be written in index form as 3^3. This is because 27 is 3x3x3 or 3^3. A common question in math will be to write a number in index form using a different number as base. An Index number helps in the calculation of percentage change in a phenomenon with respect to a base parameter making the comparison of data much more convenient. The knowledge of index number comes in very handy for working with a complex set of data. Business Mathematics and Statistics > Index Numbers. Index numbers are not directly measurable, but represent general, relative changes. They are typically expressed as percents. Examples of Index Numbers. The consumer price index is the best known index number in the United States; based on price changes for a group of selected products, it is considered to give an “average‘ value Indices & the Law of Indices Introduction. Indices are a useful way of more simply expressing large numbers. They also present us with many useful properties for manipulating them using what are called the Law of Indices. What are Indices? The expression 2 5 is defined as follows: We call "2" the base and "5" the index. Law of Indices Show the index form of 32 Check to see if the number has an integer root: The index form is a root (r) raised to a power of n. Also, we multiply r (n) times

## Index numbers are a commonly used statistical device for measuring the combined fluctuations in group-related variables. If we wish to compare the prices of consumer items today with their prices ten years ago, we are not interested in comparing the prices of only one item, but in comparing average price levels.

Laspeyres' Price index number and Paasch's Price index number Sums Maths - Now Solve Index Numbers Questions in Seconds An index number is a number which is raised to a power. The power, also known as the index, tells you how many times you have to multiply the number by itself. For example, 2 5 means that you have to multiply 2 by itself five times = 2×2×2×2×2 = 32. There are a number of important rules of index numbers: y a × y b = y a+b; Examples. 2 4 An Index number helps in the calculation of percentage change in a phenomenon with respect to a base parameter making the comparison of data much more convenient.
