# 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))`

?

radical expression for algebraic number

Simplify multiplication of SQRT()s

Laurent series, Rational Functions in sqrt(q)?

sqrt function not working properly

eliminating fractions and roots from equations

why won't simplify multiply out 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??`
