- 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!

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.

Error in variable testing condition
There's an error in the condition you specified in the Variable testing tab. Variable values can't be generated until it's fixed.

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:
Click on a note's name to show or hide it. Only shown notes will be included when you create a unit test.
No unit tests have been defined. Enter an answer above, select one or more notes, and click the "Create a unit test" button.
The following tests check that the question is behaving as desired.
This test has not been run yet This test produces the expected output This test does not produce the expected output
This test is not currently producing the expected result. Fix the marking algorithm to produce the expected results detailed below or, if this test is out of date, update the test to accept the current values.
One or more notes in this test are no longer defined. If these notes are no longer needed, you should delete this test.

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.
This part can't be reached by the student.
Add a "next part" reference to this part from another part.
None of the parts which can lead to this part are reachable either.
