I tried to rationalise the denominator to end up with j on the top of the fraction only using (1jwCR) to multiply top and bottom and I ended up with the following: Could anyone confirm or help with getting the correct answer and is there any way to simplify this further? Thank you for help.

you could simplify it a bit if you chose to $\dfrac{R}{1+(\omega R C)^2}\left(1 j \omega R C\right)$
