GCSE Maths: Worksheet Laws of Indices (Foundation.

Indices or Powers mc-TY-indicespowers-2009-1 A knowledge of powers, or indices as they are often called, is essential for an understanding of most algebraic processes. In this section of text you will learn about powers and rules for manipulating them through a number of worked examples.

Worksheet 1:8 Power Laws. Section 1 Powers In maths we sometimes like to nd shorthand ways of writing things. One such shorthand we use is powers. It is easier to write 23 than 2 2 2. The cubed sign tells us to take the number and multiply it by itself 3 times. The 3 is called the index.

Six rules of the Law of Indices: To manipulate math expressions, we can consider using the Law of Indices. These laws only apply to expressions with the same base, for example, 3 4 and 3 2 can be manipulated using the Law of Indices, but we cannot use the Law of Indices to manipulate the expressions 4 5 and 9 7 as their base differs (their bases are 4 and 9, respectively).

In the following sections, we will consider the six index laws. Index Law for Multiplication. We know that: In general: This formula tells us that when multiplying powers with the same base, add the indices. This is the first index law and is known as the Index Law for Multiplication. Example 7.

An 'index' (plural 'indices') is a number written in small case to the upper right of a number to indicate the number's size. An index is sometimes called the 'power' of a number.This worksheet tests knowledge of the'laws of indices'.

Introduction The manipulation of powers, or indices or exponents is a very crucial underlying skill to have in algebra. In essence there are just 3 laws and from those we can derive 3.
