Try this:

\documentclass{article}

\usepackage[T1]{fontenc}

\usepackage{inputenc}

\begin{document}

\begin{pspicture}(-5,-5)(5,5)

\psgrid[griddots=20,gridlabels=0pt, subgriddiv=0, gridcolor=blue!20]

\psaxes(0,0)(-5,-5)(5,5)

\psplot[algebraic, linecolor=blue]{0}{5}{sqrt(x)}

\psplot[algebraic, linecolor=red]{0.1}{5.0}{Euler^x}

\rput[lb](-4.0,3.5){\footnotesize

$S(t)=e^{\left[(-t/\alpha)^\beta\right]}$}

\rput[lb](2.0,1.0){\footnotesize $\alpha=1,\beta=1.5$}

\end{pspicture}

\end{document}

The natural exponential base is implemented as Euler. In addition, I think
there was a braces and parentheses matching problem in your label.

Good Luck!
