GCSE Secondary Maths Age 13-17 - Algebra: Indices - Explained

The video tutorial explains how to handle fractional and negative indices through two examples. In Part A, the process of converting 81 to the power of -1/2 into a positive index and then finding the square root is demonstrated. In Part B, the tutorial covers solving 64/125 to the power of 2/3 by first finding the cube root and then squaring the result. The video emphasizes understanding the steps involved in manipulating indices and provides marks for each part of the solution.
