# Derivation

1. Initial program 0.2

$\frac{1}{\sqrt{\left({e}^{\left({x}^{2}\right)} \cdot 2\right) \cdot pi}}$
2. Initial simplification0.2

$\leadsto \frac{1}{\sqrt{{e}^{\left(x \cdot x\right)} \cdot \left(pi \cdot 2\right)}}$
3. Using strategy rm
4. Applied pow1/20.1

$\leadsto \frac{1}{\color{blue}{{\left({e}^{\left(x \cdot x\right)} \cdot \left(pi \cdot 2\right)\right)}^{\frac{1}{2}}}}$
5. Applied pow-flip0.0

$\leadsto \color{blue}{{\left({e}^{\left(x \cdot x\right)} \cdot \left(pi \cdot 2\right)\right)}^{\left(-\frac{1}{2}\right)}}$
6. Using strategy rm

$\leadsto {\left(\color{blue}{\left(\left(\sqrt[3]{{e}^{\left(x \cdot x\right)}} \cdot \sqrt[3]{{e}^{\left(x \cdot x\right)}}\right) \cdot \sqrt[3]{{e}^{\left(x \cdot x\right)}}\right)} \cdot \left(pi \cdot 2\right)\right)}^{\left(-\frac{1}{2}\right)}$
8. Final simplification0.0

$\leadsto {\left(\left(2 \cdot pi\right) \cdot \left(\sqrt[3]{{e}^{\left(x \cdot x\right)}} \cdot \left(\sqrt[3]{{e}^{\left(x \cdot x\right)}} \cdot \sqrt[3]{{e}^{\left(x \cdot x\right)}}\right)\right)\right)}^{\left(-\frac{1}{2}\right)}$
