Exam-Style Question on Logarithms
A mathematics exam-style question with a worked solution that can be revealed gradually
Question id: 395. This question is similar to one that appeared on an IB Standard paper in 2019. The use of a calculator is not allowed.
(a) Solve \(4x^2 - 8x - 5 = 0\)
(b) Hence solve \(4 \times 25^x - 8 \times 5^x = 5\)
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.
