## Exam-Style Question on Indices## A mathematics exam-style question with a worked solution that can be revealed gradually |

Question id: 327. This question is similar to one that appeared on a GCSE Higher paper in 2017. The use of a calculator is not allowed.

Without using a calculator find the values of the following:

(a) \(25^{-\frac12} \)

(b) \( \left( \frac{27}{64} \right)^{ \frac23} \)

The worked solutions to these exam-style questions are only available to those who have a Transum Subscription. Subscribers can drag down the panel to reveal the solution line by line. This is a very helpful strategy for the student who does not know how to do the question but given a clue, a peep at the beginnings of a method, they may be able to make progress themselves. This could be a great resource for a teacher using a projector or for a parent helping their child work through the solution to this question. The worked solutions also contain screen shots (where needed) of the step by step calculator procedures. A subscription also opens up the answers to all of the other online exercises, puzzles and lesson starters on Transum Mathematics and provides an ad-free browsing experience. |
