log function needs an argument.Currently stuck with question 4 if anyone could provide help/answer with the relevant explanation. Image attached! Thanks.View attachment 18106
Thank you for your feedback, yes we have been told to use the change of base formula however I am struggling to find anywhere that shows the change of base formula using the format of the question.I have to guess that they made a (literal) typographical error, and meant [MATH]\log_{xy}x\cdot\log_{xy}y = \frac{1}{4}[/MATH].
You say you are stuck; where are you stuck? What did you try? Did you try, for example, using the change-of-base formula?
