Nearly spot on.

You need a bracket around root 3.

Then tidy up. Well done !!!

Not so anything. It needs to be in surds so it makes sense to work in surds not go to indices then back again. See ? So ?

Well you need to know what root 3 to the power of minus 4 is and what to do with it.

People need to grasp that 'leave it in surd form' doesn't mean 'don't simplify in the slightest'.

Of course. But why not do any simplifying into surd form not vice versa ?
Although this is a surd question it is the indices bit the OP is struggling with.

I already said that you need to tidy up the

You would not leave a question with in it - you would put 4

And you need to think about the negative index and what that means

This is just plain out and out wrong. It may be maths but it is not the way to answer this question.
