Assumption: The question should be
The answer for this is
When faced with one of these it is always worth checking if the denominator is an exact factor of the numerator. If so then you can simplify by cancelling out.
The constant in the denominator is 4. So the relation ship between 4 and the 36 in the numerator is
Any maths 'bits' should start and end with the hash symbol
You can group terms by brackets to apply the formatting required.
For this question I used:
Notice that one set of brackets group the numerator and a separate set of brackets groups the denominator.
Another example: hash sqrt(3x+1)-10 hash gives
Notice that the brackets group that which is be square rooted.
