Step 2.1

Expand $\ln (e^{0.006 x})$ by moving $0.006 x$ outside the logarithm.

$0.006 x \ln (e) = \ln (35)$

Step 2.2

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

$0.006 x \cdot 1 = \ln (35)$

Step 2.3

Multiply $0.006$ by $1$ .

$0.006 x = \ln (35)$

Step 3.3.1

Replace $e$ with an approximation.

$x = \frac{\log_{2.71828182} (35)}{0.006}$

Step 3.3.2

Log base $2.71828182$ of $35$ is approximately $3.55534806$ .

$x = \frac{3.55534806}{0.006}$

Step 3.3.3

Divide $3.55534806$ by $0.006$ .

$x = 592.55801024$
