Question

How to simplify using radical then rationalize the denominators?

Answer 1

Do you have a specific one or in general?

Answer 2

2a^-1/2

Answer 3

OK, now, they are saying "rationalize the denominators" but that does not have a denominator, so where do you think you need to start?

Answer 4

I have no clue, I'm just trying to figure out how to do it so I can do the rest

Answer 5

Well, what does a negative exponent mean?

Answer 6

o-o...

Answer 7

\(7x^{-1}=\frac{7}{x}\) That is what the negative exponent means. So what would that sort of operation do to yours?
