This video discusses the first outcome of our syllabus content. Surds and Indices are base to the chapter of Logarithms that will follow. if you have a strong grip on these and wish to study only Logs then skip to next video.
This is a 4 part series of LOGARITHM P3 which includes:

This video explain how to:
1. understand the relationship between logarithms and indices, and use the laws of logarithms (excluding change of base)
2. understand the definition and properties of e x and lnx, including their relationship as inverse functions and their graphs
3. use logarithms to solve equations and inequalities in which the unknown appears in indices
4. use logarithms to transform a given relationship to linear form, and hence determine unknown constants by considering the gradient and/or intercept.
