Hi, this is my first post.
I am having trouble with rationalising the denominator, it is really frustrating, here are some example questions of which I am finding hard to complete.

2√3-1/
√2

√5+2/
√5-2

√3+√2/
√3-√2

could you please show me the steps in answering these questions.

Thanks in advance,
Glenn
