I split this question into 4 different questions numbered 1, 2, 3 and 4.

We could split each part into its own question.

 In the statement, you do not need "is a way that", it reads fine and makes more sense without it.
 I think you should say what the large number equivalent would be for the example in the statement to make it make a link for the user. They understand what large numbers are but it is difficult to deal with them, and you showing what the large number equivalent of the example standard form will help them to understand how to use it more.
 I think you should alter the question part of a to include an example of how you would like the answer typed. I tried to type x as an * as I think many users might try, and obviously numbas didn't like that very much. If you put "Write these in standard index form (for example, a.bcd*10^n):", I think it would be clearer.
 I think you should write "the following" instead of "these" in parts a) and b), not just part c).
 I had a question in part d that technically did not follow the standard index form as A was not between 1 and 10. It was 81*10^2. If following the standard index form you had stated in the statement, it should have been 8.1*10^3.
 I think the advice for part c) could be expanded quite a bit, especially the first sentence. You haven't said what you mean by "convert".
 Minor point, but I think "Similarly" in part d) advice should have a comma after it to make it look less lonely.
 I think this is a good question!

a) and b) do not have any problems.
c)
You can input the same values in the question and get the question correct. You can fix this by making the string + and  restricted. It could also be fixed if you had a gap x 10^gap but I'm not sure if that is possible, if it were it would be a nice fix.
d) Same as above fixed by restricting the strings ( )

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.
