Question

What is the 5 over square root of 7?

Answer 1

`5/sqrt(7) = (5sqrt(7))/7`

Explanation:

We rationalize the fraction
`5/sqrt(7) = 5/sqrt(7) * sqrt(7)/sqrt(7) = (5sqrt(7))/sqrt(7)^2 = (5sqrt(7))/7`

There isn't anything left to do but evaluate, but, it's bad form to do evaluate it and you won't have any troubles just leaving it like this.
