hello to all.

this happens to be a surd but could equally apply to any algebraic equation involving fractions.

ive been asked to solve the following in the form

, where A, B and C are rational numbers.

my question is given any algebraic fraction should you always begin by multiplying the denominator?

because i get two answers depending on which way i go but only one is in the requested format, and thats the one that multiplies the denominator to start with, eg:

the other way give the correct answer if checked on a calculator but is not in the correct format

you could rationlize this surd which then give the same answer as above but this seems a bit long winded.
