P = a e^{k t}

$P = a e^{k t}$

Step 1

Rewrite the equation as

a e^{k t} = P

$a e^{k t} = P$ .

a e^{k t} = P

$a e^{k t} = P$

Step 2

Divide each term in

a e^{k t} = P

$a e^{k t} = P$ by

Step 2.1

Divide each term in

a e^{k t} = P

$a e^{k t} = P$ by

a

$a$ .

\frac{a e^{k t}}{a} = \frac{P}{a}

$\frac{a e^{k t}}{a} = \frac{P}{a}$

Step 2.2.1.1

Cancel the common factor.

$\frac{a e^{k t}}{a} = \frac{P}{a}$

Step 2.2.1.2

Divide

$e^{k t}$ by

$1$ .

$e^{k t} = \frac{P}{a}$

$e^{k t} = \frac{P}{a}$

$e^{k t} = \frac{P}{a}$

$e^{k t} = \frac{P}{a}$

Step 3

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

$\ln (e^{k t}) = \ln (\frac{P}{a})$

Step 4

Expand the left side.

Step 4.1

Expand

$\ln (e^{k t})$ by moving

$k t$ outside the logarithm.

$k t \ln (e) = \ln (\frac{P}{a})$

Step 4.2

The natural logarithm of

$e$ is

$1$ .

$k t \cdot 1 = \ln (\frac{P}{a})$

Step 4.3

Multiply

$k$ by

$1$ .

$k t = \ln (\frac{P}{a})$

$k t = \ln (\frac{P}{a})$

Step 5

Divide each term in

$k t = \ln (\frac{P}{a})$ by

$k$ and simplify.

Step 5.1

Divide each term in

$k t = \ln (\frac{P}{a})$ by

$k$ .

$\frac{k t}{k} = \frac{\ln (\frac{P}{a})}{k}$

Step 5.2.1.1

Cancel the common factor.

$\frac{k t}{k} = \frac{\ln (\frac{P}{a})}{k}$

Step 5.2.1.2

Divide

$t$ by

$1$ .

$t = \frac{\ln (\frac{P}{a})}{k}$

$t = \frac{\ln (\frac{P}{a})}{k}$

$t = \frac{\ln (\frac{P}{a})}{k}$

$t = \frac{\ln (\frac{P}{a})}{k}$
