Solve 13^2x+1=6

$$13 ^ { 2 x + 1 } = 6$$

Solve for x

$$x=\frac{\log_{13}\left(6\right)-1}{2}\approx -0.150722252$$

Steps Using Definition of Logarithm

Use the rules of exponents and logarithms to solve the equation.

$$13^{2x+1}=6$$

Take the logarithm of both sides of the equation.

$$\log(13^{2x+1})=\log(6)$$

The logarithm of a number raised to a power is the power times the logarithm of the number.

$$\left(2x+1\right)\log(13)=\log(6)$$

Divide both sides by \log(13).

$$2x+1=\frac{\log(6)}{\log(13)}$$

By the change-of-base formula \frac{\log(a)}{\log(b)}=\log_{b}\left(a\right).

$$2x+1=\log_{13}\left(6\right)$$

Subtract 1 from both sides of the equation.

$$2x=\log_{13}\left(6\right)-1$$

Divide both sides by 2.

$$x=\frac{\log_{13}\left(6\right)-1}{2}$$

Solve for x (complex solution)

$$x=\frac{\pi n_{1}i}{\ln(13)}+\frac{\log_{13}\left(6\right)}{2}-\frac{1}{2}$$

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