Saved a checkpoint:
I've changed the last part to a "choose several from a list" type, because it makes more sense.
I've also reworded the advice a bit.

Do each of the subparts assess different things? If not, you might as well just have one of each  the student can click "try another question" if they want more.
The advice for part c doesn't show how to enter the answer. Students can't type $\sqrt[4]{x}$, so you need to say something like, "enter this as
x^(1/4)
", or add a line "$ = x^{1/4}$" to the end of the workingout.I'm not keen on the sudden appearance of $n$ in the advice for part d! I think you're just shuffling things around to show what you've already been given. The expressions you have to resolve are all just stock identities, so I don't think there's anything to explain.

 There is a typo in the question statement (logaTrithms).
 There should be a blank space before a Gap in all parts like you did in part b.ii) so it looks neater.
 In part c), the answer x= isn't in LaTeX as it should ($x=$).
 I feel like in part d), it would be nice to specifically state you need to choose one from each row, without it maybe some students may get confused and they may possibly only pick one from each column.
 In Advice part b) in ii), the expression that follows after "And our equation as,..." is the correct answer for part i), not part ii). You may just need to change your variables in this expression in your code for advice to variables from part ii).
 In part c), you refer to part b). I think it should say part b) with the bracket instead of just part b. Also, are you sure you want 1 to be a possible value of variable h2? It is completely up to you but I just find " $x = \sqrt[1]{a}$ " a bit confusing as the last line of the solution when h2 = 1.
 In part d), "Evaluating $e^{\lnx}$," should be "Evaluating $e^{\ln(x)}$,"  you need to add brackets around x in \lnx. Hope this helps.

$\log$ should be roman, rather than $log$ and the there's actually a command
\log
that you can use. Similarly with $\ln$, use\ln.
The statement could be used to offer an introduction to the topic (changing the subject of a an equation with logs).
In the advice, for completeness I think you should include all of the solutions. If you don't want to include the same amount of detail, because there is nothing new to explain, then you could say "Similarly, ..." followed by oneline solutions.
In (d) you reference i),ii)..., but this numbering is not used in the question itself. You also give out some definitions which are required. These should be placed into a step to give the student an opportunity to glean this information when they are attempting the question.

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.
