Powers and Roots
Subjects / Maths / Number
This title looks at powers, indices and roots, and this is a topic that can be tested on both the non calculator paper and the calculator paper. Chapter One looks at standard square and cube numbers, along with their corresponding roots. Indices, or powers, can be used to do calculations very quickly. Without a calculator, we follow the index laws and work out the highest common factors and lowest common multiples of different numbers. Standard Index Form, covered in Chapter Three, is a way of writing big and small numbers. This is one area that can occur on both papers. Chapter Four is for higher level only. Here, we consider how reciprocals can be written using negative indices. Finally, we have generated some typical exam questions for you to practise in the 'Test Yourself' chapter.
