Where it says shown below. I am hoping to insert GIFs of the explanation above. I am going to do this over the weekend; if it works i'll insert it if not I will omit the line and gap.

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.

Advice:

a) The advice for part a does not match the question. You could also possibly show another method of multiplying by the denominator to realise the bottom; I could be overcomplicating it with this alternative method, so it is up to you.
b) I would put the 12 in '12 is the denominator' in math mode. Not sure what the last line means I think it is suppose to read $\frac{\sqrt{ab}}{1}$ but reads as $\frac{\sqrt{ab}}{[1,1,1,1,1]}$.
c) Is good
d) There could be some confusing with the wording, "this is the denominator with a changed sign." It could be interpretted as the whole denominator changing signs; I would possibly change it to the rational term sign changed, or something to that effect.
