$$\pi \approx 3$$ (holds for small values of &pi; and large values of 3)

Another (more complex) LaTEX code example: \pi \approx (\ln 6)^{(\ln 5)^{(\ln 4)^{(\ln 3)^{\ln 2}}}}

$$\pi \approx (\ln 6)^{(\ln 5)^{(\ln 4)^{(\ln 3)^{\ln 2}}}}$$

$$a^{x+y} = a^x \cdot a^y = a^y \cdot a^x = a^{y+x}$$ (Law of Commutation) $$\,\! \ln(e^x) = x\cdot \ln(e^1) = x\cdot \ln(e) = x\cdot 1 = x$$
