Hi all,
A quick question.

Do you expect something else? The result appears to be correct.
Please note that, when dealing with square or cubic roots, Raku will not
use rationals, but ordinary floats.

Did you mean the square root of 9 to give 3. Maybe you were wanting cube
root of 27?
Using REPL, I got

You have several useful answers.
I want to summarize what they saButy, and add a couple resources.
* You probably meant 9 ** <1/2>.
Which will display 3.
But it's a Num. It's not the right type if you care about accuracy.
* A solution to get rationals right is built into Raku.
