Solucionar sigma_x^2=(-2-0)^alpha*4/9+(0*0)^2*3/9+(1*0)

$$\sigma _ { x } ^ { 2 } = ( - 2 - 0 ) ^ { \alpha } \times \frac { 4 } { 9 } + ( 0 \times 0 ) ^ { 2 } \times \frac { 3 } { 9 } + ( 1 \times 0 )$$

Resolver para α (solución compleja)

$$\alpha =\frac{2\left(\ln(\sigma _{x})+\ln(\frac{3}{2})\right)}{\ln(2)+\pi i}+\frac{2\pi n_{1}i}{\ln(2)+\pi i}$$

$$n_{1}\in \mathrm{Z}$$

$$\sigma _{x}\neq 0$$

Resolver para σ_x (solución compleja)

$$\sigma _{x}=-\frac{2\left(-2\right)^{\frac{\alpha }{2}}}{3}$$

$$\sigma _{x}=\frac{2\left(-2\right)^{\frac{\alpha }{2}}}{3}$$

Resolver para α

$$\alpha =\frac{\ln(\sigma _{x}^{2})+\ln(\frac{9}{4})}{\ln(2)}$$

$$\sigma _{x}\neq 0\text{ and }Numerator(\frac{\ln(\sigma _{x}^{2})+2\ln(3)}{\ln(2)}-2)\text{bmod}2=0\text{ and }Denominator(\frac{\ln(\sigma _{x}^{2})+2\ln(3)}{\ln(2)})\text{bmod}2=1$$

Resolver para σ_x

$$\sigma _{x}=\frac{2\sqrt{\left(-2\right)^{\alpha }}}{3}$$

$$\sigma _{x}=-\frac{2\sqrt{\left(-2\right)^{\alpha }}}{3}\text{, }Denominator(\alpha )\text{bmod}2=1\text{ and }\left(-2\right)^{\alpha }\geq 0$$
