Saved a checkpoint:
It looks like parts e and f had some constant coefficients in the advice which weren't present in the actual question, so I've removed those.
Otherwise, this looks good!

 I would scrap the first sentence of the statement. It should be in the description. I think I would just write "Using the laws of indices, simplify each expression down to its simplest form." The bit that you have afterwards that states "Recall that a^0=1..." didn't apply to any of the questions I was given, and it seems to be a random place to have this bit of info.
 In part c), you suggested that the user could use the rule a^m=1/a^m but when I tried to write my answer in that form it did not accept it. I wouldn't suggest you suggest to the user to use the second rule.
 Typo in part b) of the advice  explicity instead of explicitly.
 I'm not sure, but I don't know if the advice for the alternative method of part c) is correct or clear enough. I thought that that rule was a way of reorganising the fraction rather than actually calculating stuff and that if you used it, the final answer of (8a^4)/(3a^6) would be 8/(3a^2) not 8/3(a^2). I may well be wrong hahaha so just ignore me if so!
 I think you're missing a \displaystyle in part e) of the advice.
 I think the bit you have written at the end of part e) "This can be simplified further if possible." is a bit random. I would scrap it.
 I think you're missing some displaystyles in part f) of the advice as well.
 I think generally the question is very good and the advice is very clear and concise!

Advice:
For all parts, not 100% sure on this but personally I would omit the commas after each line of the equation and just have some punctuation at the end such as a full stop or comma like you have done, just not every line.
a) Very good
b) To read easier I would remove 'Then' from the first line and 'that' from the second. Also possibly but 'Therefore' (the one before the equation) on another line.
All other parts were good just the commas in the equations.

Thanks for the feedback Aiden, think i should have fixed all of the string restrictions now.

a) Inputting the question gives the correct answer this can be fixed by restricting the string *
b) As above
c) Restrict strings ( )
d) As above
e) and f) are good. Rest of the question is good just the string parts.

This mainly looks good.
Try to avoid long runs of maths inline with text  they're quite hard to read. Put long bits of maths in display mode, and don't be afraid to use lots of paragraph breaks.

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.
