Indices (the plural of index) are the lazy mathematician’s way of abbreviating operations such as multiplication and division. You do not have to use this technique if you have the time to do otherwise. For example, the lazy mathematician might write x6, whereas you could write x × x × x × x × x × x.

The laws of indices. Introduction. A power, or an index, is used to write a product of numbers very compactly. The plural of index is indices. 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. Indices (the plural of index) are the lazy mathematician’s way of abbreviating operations such as multiplication and division. You do not have to use this technique if you have the time to do otherwise. For example, the lazy mathematician might write x6, whereas you could write x × x × x × x × x × x. the base and add the indices. ² am an = am¡n, a 6=0 To divide numbers with the same base, keep the base and subtract the indices. ² (a m)n = a £n When raising a power to a power, keep the base and multiply the indices. Simplify using the laws of indices: a 23 £22 b x4 £x5 a 23 £22 =23+2 =25 =32 b x4 £x5 = x4+5 = x9 B INDEX LAWS Example. Worksheet 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. Then means multiply 10 by itself 6 times. After reading this text, and/or viewing the video tutorial on this topic, you should be able to: •simplify expressions involving indices •use the rules of indices to simplify expressions involving indices •use negative and fractional indices. 1. Introduction 2 2. The ﬁrst rule: am × an = am+n 3 3.
