Surds and indices are traditionally two of the topics that students find most challenging, but these resource should help provide interesting, varied ways of helping students develop the key skills they need. Surds are numbers left in square root form that are used when detailed accuracy is required in a calculation. They are numbers which, when written in decimal form, would go on forever. Part of Standard form. Standard form, or standard index form, is a system of writing numbers which can be particularly useful for working with very large or very small numbers. It is based on using powers of 10 to express how big or small a number is. Standard form is written in the form of , where is a number bigger than or equal to 1 and less than 10. Indices and Surds. Definition. An index (plural: indices) is the power, or exponent, of a number. For example, a3 a^3 a3 has an index of 3. A surd is an irrational number that can be expressed with roots, such as 2 \sqrt{2} 2 or 195 \sqrt[5]{19} 519.

PPT with teacher examples and pupil questions/answers including: Introduction to Indices Basic Laws Exam Ques 1 (N5), Indices & Surds (With Answers) A Surds exam question where you are asked to “express as a surd in its simplest form” is shown below. Standard index form is a way of writing and calculating with very large and small numbers. A secure understanding of place value is needed to access this. Surds are square roots that cannot exactly in fraction form. This unit of work contains work on: - Index Laws - Standard Form - Rational Numbers and Reciprocals - Recurring Decimals - Simplifying Surds - This is a unit of work I have put together for a high-ability Year 10 group. • Apply index laws to evaluate arithmetic expressions. • Apply index laws to simplify algebraic expressions. • Use standard (scientific) notation to write small and large numbers. • Understand the difference between rational and irrational numbers. • Perform operations with surds and indices.

It has an infinite number of non-recurring decimals. It has an infinite number of non-recurring decimals. Therefore, surds are irrational numbers.

Revision:Indices and Surds. Indices are used to describe the general term for in say . There are a few laws to know when manipulating expressions involving indices. Indices, Surds, and Logarithms. Many laws to learn for this chapter! The first time I learnt indices and logarithms, I couldn't understand it at all. But just memorize those laws and learn to apply them correctly. Don't worry, you will get the hang of it very soon. =) Surds and indices are traditionally two of the topics that students find most challenging, but these resource should help provide interesting, varied ways of helping students develop the key skills they need. Surds are numbers left in square root form that are used when detailed accuracy is required in a calculation. They are numbers which, when written in decimal form, would go on forever.

A surd is an irrational number that can be expressed with roots, such as 2 \sqrt{2} 2 or 195 \sqrt[5]{19} 519. 25 INDICES, STANDARD FORM AND SURDS 610 In this chapter you will: work out the value of an expression with zero, negative or fractional indices convert between standard form and ordinary numbers calculate with numbers in standard form manipulate surds make estimates to calculations using numbers in standard form.
