1 Log 3 Using the log rules, write the following in terms of p, q, and r.

2 Division Rule

3 multiplication Rule

4 a) b) c) d) e) f)

5 a) b) c) d) e) f) g) h) i)

6 Log 3 Know how to solve equations with logs Understand what a hidden quadratic is Be able to spot a hidden quadratic

7 Using rules to solve equations Remember, when solving equations with logs, or exponentials, you want to end up with: OR

8 Example: Find x Power Rule X on 1 side X as a factor Multiplication Rule Ended up with log on 1 side

9 Example: Find x Power Rule Change to index form Solve for X Ended up with log on 1 side

10 Example: Find x Power Rule Get all X on 1 side Power & Division Rule Ended up with log both sides

11 Example: Find x Power & Division Rule Ended up with log both sides Get rid of log on both sides, solve equation

12 Have a go at the exam questions

13 LOGS - Hidden Quadratics A hidden quadratic is one that is made from rearranging or working.

14 Have a go at the exam question

15 Exponentials - Hidden Quadratics In your exams, you might come across something like this. This is also a hidden quadratic.

16 Exponentials - Hidden Quadratics These will be your hardest questions on the paper. They require using the indices rules, along with many others (like logs) The hardest part is just setting it up.

17 Exponentials - Hidden Quadratics

18

19 Best way to identify these is if there is two powers, and one is double the other

20 Exponentials - Hidden Quadratics Best way to identify these is if there is two powers, and one is double the other YOU MUSTN’T FORGOT TO PROVE THE SQUARE PART!!!
