This question had an unwieldy part b), asking the student to simplify an expression containing many log terms. This was set up in an extraordinarily complicated way with over a dozen variables and, as I'm sure we have other similar questions written in a less complex way, I have removed it and reorganised part a) to become two parts. The question is very straightforward now, but I think that's OK.

Saved a checkpoint:
Edited some of the advice and added the simplified answer to the advice (with visibility so if gcd of the numerator and denominator = 1 it will only show that and not try to simplify).

This looks like a good question i just have a few comments.
In the statement you might need to have a comma after you state the first law of logarithms.
Main Parts
a) good
b) are you wanting the student to input their answer as a simplified fraction or just any fraction? you might need to put in a precision restriction.
Advice
a) i) good, just a typo "subsituting" should be "substituting".
a) ii) same typo as in a) i)
I think the have typed up the wrong questions for the advice here, i'm not sure where the a) ii) part fits in
I think the advice for a) iii) is meant to be for question a) ii) but the numbers here aren't the same as in the question.
Also you have two a) iii)s in the advice, but there are only two questions in part a) in the actual question.
b) i) you might need a full stop after the first line of maths here.
b) ii) again you might need a full stop after the first line of maths.
One of the logs here is in italics as well whereas the others aren't.
Also the final answer in the advice here is not given as a simplified fraction.

Part b) asks for the answers as a fraction, but the gaps do not accept fraction input. In addition, the correct answer is displayed as a decimal. Tick the "Allow the student to enter a fraction?" checkbox, which will also reveal an option to display the answer as a fraction.
In the advice, rather than
(...)
, use\left(
and\right)
for parentheses, which scale to the height of the contents.The pairs (i),(ii) and (iii),(iv) in part a) don't really ask anything different, but I think that's OK. You could have (iv) result in a fraction, though then you will need to add "Enter your answer as a fraction where appropriate" or similar in the part prompt.
Otherwise this is good.

The gaps should be number entry parts, not mathematical expressions.

Test that the marking algorithm works
Check that the marking algorithm works with different sets of variables and student answers using the interface below.
Create unit tests to save expected results and to document how the algorithm should work.
There's an error which means the marking algorithm can't run:

When you need to change the way this part works beyond the available options, you can write JavaScript code to be executed at the times described below.
To account for errors made by the student in earlier calculations, replace question variables with answers to earlier parts.
In order to create a variable replacement, you must define at least one variable and one other part.
Variable  Answer to use  Must be answered?  

The variable replacements you've chosen will cause the following variables to be regenerated each time the student submits an answer to this part:
These variables have some random elements, which means they're not guaranteed to have the same value each time the student submits an answer. You should define new variables to store the random elements, so that they remain the same each time this part is marked.
