The notation and is known as index form. The small digit is called the index number or power. You have already seen that and that . Similarly, (five to the power of ) and (three to the power of ) . The index number tells you how many times the number should be multiplied. When the index number is two, the number has been squared. In this tutorial you are shown the division rule for indices where the power remains positive. x m ÷ x n = x m-n Rotate to landscape screen format on a mobile phone or small tablet to use the Mathway widget, a free math problem solver that answers your questions with step-by-step explanations . Indices. This section covers Indices revision. 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: Simplifying expressions using the laws of indices Indices show where a number has been multiplied by itself, eg squared or cubed, or to show roots of numbers, eg square root. Indices - Introduction Indices, exponents or powers are numbers that tell us how often a number is to be multiplied by itself in a mathematical expression. A power is usually represented by a raised smaller number on the right side of the number that it belongs to (eg: 3²). The example on the right shows the function of a power more clearly. Indices are used to show numbers that have been multiplied by themselves. They can be used instead of the roots such as the square root. The rules make complex calculations that involve powers easier.

Activities and questions that students can work on to discover the square numbers for themselves. Square & Cube Numbers Puzzle Free resource Worksheet | Positive & Negative Indices Odd One Out* Some activities include algebra.

Maths : Indices : Multiplication Rule In this tutorial you are shown the multiplication rule for indices. You are given a short test at the end. x m × x n = x m+n Simplifying expressions using the laws of indices Indices show where a number has been multiplied by itself, eg squared or cubed, or to show roots of numbers, eg square root. If you have no problem with this type of expression, you can consider yourself a very accomplished mathematician in the area of fractions and indices. Trying Some Surds Now that you have studied simple, fractional and negative indices, you can try to do some surds. Surds involves using square roots and relates to the indices.

or laws, which can be used to simplify expressions involving indices. 1. Powers, or indices Without using a calculator work out the value of a) 42, b) 53, c) 25,.

21 Mar 2014 Modern Engineering Mathematics. 4 th ed. Harlow: Prentice Hall -Pearson Education. This section covers Indices and the uses of Indices in algebra. After studying this section, you will be able to: divide and multiply algebraic expressions using indices; find roots using indices. This video shows a guide to indices and powers. Multiplying and dividing indices, raising indices to a power and using standard form are explained.

this implies that you should give the answer in terms of constants, trig functions and square roots instead of working out an imprecise decimal approximation.

Indices - Introduction Indices, exponents or powers are numbers that tell us how often a number is to be multiplied by itself in a mathematical expression. A power is usually represented by a raised smaller number on the right side of the number that it belongs to (eg: 3²). The example on the right shows the function of a power more clearly. Indices are used to show numbers that have been multiplied by themselves. They can be used instead of the roots such as the square root. The rules make complex calculations that involve powers easier. Law of Indices. To manipulate 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 3 5 and 5 7 as their base differs (their bases are 3 and 5, respectively).

Indices are used to show numbers that have been multiplied by themselves. They can be used instead of the roots such as the square root. The rules make complex calculations that involve powers easier.

An example of a fractional index is . The denominator of the fraction is the root of the number or letter, and the numerator of the fraction is the power to raise the answer to. By using multiplication rules it is clear to see that: Therefore: In general, , and so on. Exponents are also called Powers or Indices. Let us first look at what an "exponent" is: The exponent of a number says how many times to use the number in a multiplication. In this example: 8 2 = 8 × 8 = 64. In words: 8 2 can be called "8 to the second power", "8 to the power 2" How to work with indices (powers).wmv - Duration: More advanced indices practice questions and answers The Maths and Chemistry Man 29,094 views. 11:58.
