The aim of this game is to match pairs of cards. Click on a 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. Covers expressing number in index form. We know that: So, we can write 8 as 2 3.. Likewise, 27 can be written as 3 3 and 125 can be written as 5 3.. So far, we have considered numbers that have a group of the same factors.Sometimes, a number has more than one group of the same factors as shown in the following example.

## In this leaflet we remind you of how this is done, and state a number of rules, or laws, which can be used to simplify expressions involving indices. 1. Powers, or

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.) Definition of index in the Definitions.net dictionary. Meaning of index.

the small number is called an exponent, index, power or order, e.g. 10 x 10 x 10 x 10 = 104. EXAMPLES: index notation or exponential form Do they have to be whole numbers? What does an index of zero mean? Calculations. Now that we have a great, compact way of writing long products we can start What are Indices? The expression 25 is defined as follows: We call "2" the base and "5" the index.
