Axiom

$$
y={\sqrt {{{{e \sp {x \sp 2}}+{e \sp {\left( -{x \sp 2}
\right)}}}
\over {{x \  {\sqrt {3}}} -{\sqrt {2}}}}}}
\leqno(36)
$$

Macsyma

% Y = SQRT((%E^X^2+%E^-X^2)/(SQRT(3)*X-SQRT(2)))
$$ y=\sqrt{{{e^{x^{2}}+e^ {-{ x^{2} }}}\over{\sqrt{3}\,x-\sqrt{2}}}} $$

Maple

$$
y=\sqrt {{\frac {{e^{{x}^{2}}}+{e^{-{x}^{2}}}}{\sqrt {3}x-\sqrt {2}}}}
$$

Mathematica

$$
y = {\sqrt{{\frac{{e^{-{x^2}}} + {e^{{x^2}}}}
          {-{\sqrt{2}} + {\sqrt{3}}\,x}}}}
$$

MuPAD

$$
y = \sqrt{\frac{\mbox{exp}\left(x^2\right) + \mbox{exp}\left(- x^2\right)}{- \sqrt{2} + x \sqrt{3}}}
$$

Reduce

\begin{displaymath}
\sqrt {\left(e^{2 x^{2}}+1\right)/\left(e^{x^{2}} \sqrt {3} x-e^{x^{2}}
\sqrt {2}\right)}
\end{displaymath}

\begin{displaymath}
\sqrt {\left(\exp \left(x^{2}\right)+\exp \left(-x^{2}\right)\right)/\left(
\sqrt {3} x-\sqrt {2}\right)}
