$\frac{\ln (1.2) t}{0.04}$

Step 1

Factor $\ln (1.2)$ out of $\ln (1.2) t$ .

$\frac{\ln (1.2) (t)}{0.04}$

Step 2

Factor $0.04$ out of $0.04$ .

$\frac{\ln (1.2) (t)}{0.04 (1)}$

Step 3

Separate fractions.

$\frac{\ln (1.2)}{0.04} \cdot \frac{t}{1}$

Step 4

Replace $e$ with an approximation.

$\frac{\log_{2.71828182} (1.2)}{0.04} \cdot \frac{t}{1}$
