Working with Indices Chapter 2. 2 4, 16 and 32 are all powers of

Working with Indices Chapter 2. 2 4, 16 and 32 are all powers of 2 You need the same base number to add powers Base Index Power Standard Form

Working with Indices Start by writing each number as a product of its prime

Working with Indices Start by writing each number as a product of its prime factors. Comparing powers, this gives the pair of simultaneous equations: Chapter 2. 2 Base Index Power Standard Form

Working with Indices Chapter 2. 2 This can be written as: Base Index Power

Working with Indices Chapter 2. 2 This can be written as: Base Index Power Standard Form

Working with Indices Chapter 2. 2 This expression is: Base Index Power Standard Form

Working with Indices Chapter 2. 2 This expression is: Base Index Power Standard Form

Working with Indices Light travels at a speed of 300 million metres per second.

Working with Indices Light travels at a speed of 300 million metres per second. At a certain time Pluto is 5. 4 terametres from Earth. How many hours does it take light to travel from Pluto to Earth? Time taken Base Index Power Standard Form Chapter 2. 2 There are 60 x 60 seconds in an hour

Using and Manipulating Surds The largest square number which is a factor of 32

Using and Manipulating Surds The largest square number which is a factor of 32 is 16. Chapter 2. 1 Multiply out the brackets. It’s a good idea to write the positive term first since it is easy to lose a minus sign at the start of an expression. Collect like terms. Surd Simplest Form Rationalise Denominator
