Very nearly there!

Add restrictions to the parts forbidding brackets, to make sure the student has expanded in some way. It'll be too much effort to make sure they've collected like terms in the later parts.

In the parts with more than one variable, make sure you set the "expected variable names" field, so that mistakes like typing ab instead of a*b get caught.

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.

- 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.

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 ( )
