The video below is from the Solving Equations sub topic. It has my solution to Question 5 from the 2013 VCAA Maths Methods Short Answer exam. This type of question relies on an understanding of the log and index laws and which ones to use when solving log & exponential equations. You also need good algebra skills to get the correct answer – 54% of students answered part a correctly and 64% answered part b correctly.
