Pagpalitin ang magkabilang panig para nasa kaliwang bahagi ang lahat ng variable na term.

$$5^{x}=80430587335437951845921127710495140134505930956790981674787620735993532493360592592242243732067646706109375636523120697559743178513198594503598322878201257201714879929710377837182022631168365478515625$$

Kunin ang logarithm ng magkabilang dulo ng equation.

$$\log(5^{x})=\log(80430587335437951845921127710495140134505930956790981674787620735993532493360592592242243732067646706109375636523120697559743178513198594503598322878201257201714879929710377837182022631168365478515625)$$

Ang logarithm ng isang numero na na-raise sa isang power ay ang power times ang logarithm ng numero.

$$x\log(5)=\log(80430587335437951845921127710495140134505930956790981674787620735993532493360592592242243732067646706109375636523120697559743178513198594503598322878201257201714879929710377837182022631168365478515625)$$

I-divide ang magkabilang dulo ng equation gamit ang \log(5).

$$x=\frac{\log(80430587335437951845921127710495140134505930956790981674787620735993532493360592592242243732067646706109375636523120697559743178513198594503598322878201257201714879929710377837182022631168365478515625)}{\log(5)}$$

Gamit ang change-of-base formula na \frac{\log(a)}{\log(b)}=\log_{b}\left(a\right).

$$x=\log_{5}\left(80430587335437951845921127710495140134505930956790981674787620735993532493360592592242243732067646706109375636523120697559743178513198594503598322878201257201714879929710377837182022631168365478515625\right)$$

I-solve ang x (complex solution)

$$x=\frac{2\pi n_{1}i}{\ln(5)}+286$$

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