$3 = e^{2 t}$

Step 1

Rewrite the equation as $e^{2 t} = 3$ .

$e^{2 t} = 3$

Step 2

Take the natural logarithm of both sides of the equation to remove the variable from the exponent.

$\ln (e^{2 t}) = \ln (3)$

Step 3

Expand the left side.

Step 3.1

Expand $\ln (e^{2 t})$ by moving $2 t$ outside the logarithm.

$2 t \ln (e) = \ln (3)$

Step 3.2

The natural logarithm of $e$ is $1$ .

$2 t \cdot 1 = \ln (3)$

Step 3.3

Multiply $2$ by $1$ .

$2 t = \ln (3)$

Step 4

Divide each term in $2 t = \ln (3)$ by $2$ and simplify.

Step 4.2.1.1

Cancel the common factor.

$\frac{2 t}{2} = \frac{\ln (3)}{2}$

Step 4.2.1.2

Divide $t$ by $1$ .

$t = \frac{\ln (3)}{2}$

Step 5

The result can be shown in multiple forms.

Exact Form:
