Description

Describe what this variable represents, and list any assumptions made about its value.

Can an exam override the value of this variable?

Generated value: `integer`

← Depends on:

This variable doesn't seem to be used anywhere.

Parts

Part a) Gap-fill
1. Gap Mathematical expression
  Add
Part b) Choose several from a list

Gap-fill

Ask the student a question, and give any hints about how they should answer this part.

Rearrange the equation to find $x$ .

$\log_\var{f}(x)=\var{f1}$

$x=$ Unnamed gap
