WebbDividing Indices. Here we will learn about dividing indices including how to use the laws of indices to divide indices and how to divide indices that have different bases.. There are also laws of indices worksheets based on Edexcel, AQA and OCR exam questions, along with further guidance on where to go next if you’re still stuck. WebbThe index laws apply to fractional indices as well as positive and negative integer indices. Using the first index law we know that 3 × 3 = 31 = 3 That is 3 multiplied by itself equals 3. The square root of 3, √3 is also a number that, when multiplied by itself, equals 3: √√3 × 3 = 3 √Since √3 behaves like 3 we say that 3
WebbWe cannot simplify them using the laws of indices as the bases are not the same. Write out each term without the indices; Work out the calculation; E.g. To evaluate the following expression: \[2^{3} \times 3^{2}\] We need to write each term of the calculation without using index notation. WebbIndex laws allow us to simplify an expression involving multiple indices. Powers of the Same Base The table below summarises the basic index laws. Note that, these laws only apply for powers on the same base. When multiplying powers of the same base, we can simply add the powers together. For example:
