Solve (3/2)^x=2

$$( \frac { 3 } { 2 } ) ^ { x } = 2$$

Solve for x

$$x=\log_{\frac{3}{2}}\left(2\right)\approx 1.709511291$$

Steps Using Definition of Logarithm

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

$$\left(\frac{3}{2}\right)^{x}=2$$

Take the logarithm of both sides of the equation.

$$\log(\left(\frac{3}{2}\right)^{x})=\log(2)$$

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

$$x\log(\frac{3}{2})=\log(2)$$

Divide both sides by \log(\frac{3}{2}).

$$x=\frac{\log(2)}{\log(\frac{3}{2})}$$

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

$$x=\log_{\frac{3}{2}}\left(2\right)$$

Solve for x (complex solution)

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

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