$\ln (\frac{0.5}{2.6}) = (- \frac{\ln (2)}{5730}) t$

Step 1

Rewrite the equation as $- \frac{\ln (2)}{5730} t = \ln (\frac{0.5}{2.6})$ .

$- \frac{\ln (2)}{5730} t = \ln (\frac{0.5}{2.6})$

Step 2

Step 2.1

Combine $t$ and $\frac{\ln (2)}{5730}$ .

$- \frac{t \ln (2)}{5730} = \ln (\frac{0.5}{2.6})$

Step 3

Move all the terms containing a logarithm to the left side of the equation.

$- \frac{t \ln (2)}{5730} - \ln (\frac{0.5}{2.6}) = 0$

Step 4

Divide $0.5$ by $2.6$ .

$- \frac{t \ln (2)}{5730} - \ln (0.1\overline{923076}) = 0$

Step 5

Add $\ln (0.1\overline{923076})$ to both sides of the equation.

$- \frac{t \ln (2)}{5730} = \ln (0.1\overline{923076})$

Step 6

Multiply both sides of the equation by $- 5730$ .

$- 5730 (- \frac{t \ln (2)}{5730}) = - 5730 \ln (0.1\overline{923076})$
