The only way that I am aware of without using any LaTeX-based terminal
is to use the Unicode character SQUARE ROOT (U+221A)

set terminal pdfcairo enhanced
set encoding utf8
set ylabel '√x'
set output 'test.pdf'
plot sin(x)

or with the Symbol font (see ps_guide.ps):

set terminal postscript eps enhanced
set ylabel '{/Symbol \326}x'
set output 'test.eps'
plot sin(x)


With a LaTeX-based terminal you could do

set terminal epslatex standalone
set ylabel '$\sqrt{x}$'
set output 'test.tex'
plot sin(x)

latex test.tex && dvips test.dvi && ps2pdf test.ps
