# formatting fractions involving square roots

How can I tell sage that I want the result to be shown as $\frac{1}{\sqrt{3}}$ rather than $\frac13\sqrt3$ when I type `show(1/sqrt(3))`

?

formatting fractions involving square roots

`show(1/sqrt(3))`

why won't simplify multiply out square roots?

Simplify multiplication of SQRT()s

eliminating fractions and roots from equations

strange way to simplify square roots

dividing vector(a,b) by sqrt(x) gives (a/x*sqrt(x),b/x*sqrt(x))

Not really convenient but it gives the expected answer:

`show(sqrt(3).power(-1,hold=True))`

.Thanks, that is at least something. While playing with this, I noticed that

`power?`

and`power??`

documentation does not mention the`hold`

keyword at all.Searching for hold=True I just found https://ask.sagemath.org/question/757..., which makes this question a duplicate.

You have to look for

`power`

as a method of an expression, for example:`x.power?`

or`pi.power??`
