Question in Bill's workspace
Express $\log_a(x^{c}y^{d})$ in terms of $\log_a(x)$ and $\log_a(y)$. Find $q(x)$ such that $\frac{f}{g}\log_a(x)+\log_a(rx+s)-\log_a(x^{1/t})=\log_a(q(x))$.

Question in How-tosThis question shows how to make the correct answer to a "choose one from a list" part depend on randomised question variables, in a couple of ways. The first part uses JME expressions to define the marks available for each choice. The second part uses the "custom marking matrix" option.
