So, given that you can't show me the exact problem I will assume you have one of two situations. I will list both of them below and you can use the assumption that's correct for your problem.
Note: The way you wrote the question makes me think that I may be assuming wrong, so, I'll be solving two problems just in case
ASSUMPTION 1:
Given: 3 / sqrt( 5 )
Simplify.
------------------------------------------
◼︎ 3 / sqrt( 5 ) ; starting with the original problem
◼︎ 3 / sqrt( 5 ) ; ANSWER.
(There is nothing to change. The
problem is as simple as it can
get. sqrt(5) is not possible to
simplify and 3 / sqrt( 5 ) is
not possible to simplify since one
has a root and the other doesn't)
ASSUMPTION 2:
Given: sqrt( 3 / sqrt( 5 ) )
Simplify.
------------------------------------------
◼︎ sqrt( 3 / sqrt( 5 ) ) ; starting with the original problem
◼︎ sqrt( 3 ) / sqrt( sqrt( 5 ) ) ; applied a radical rule to split
the root symbol into two, one for
the numerator and one for the
denominator.
◼︎ sqrt( 3 ) / ( 5 )^(1/4) ; ANSWER.
( simplified the denominator. Two
sqaure roots multiply to yield you
the power of (1/4) )
