$- 10 \ln (\frac{85.3 - 70}{98.6 - 70})$

Step 1

Rewrite $\ln (\frac{85.3 - 70}{98.6 - 70})$ as $\ln (85.3 - 70) - \ln (98.6 - 70)$ .

$- 10 (\ln (85.3 - 70) - \ln (98.6 - 70))$

Step 2

Subtract $70$ from $98.6$ .

$- 10 (\ln (85.3 - 70) - \ln (28.6))$

Step 3

Subtract $70$ from $85.3$ .

$- 10 (\ln (15.3) - \ln (28.6))$

Step 4

Apply the distributive property.

$- 10 \ln (15.3) - 10 (- \ln (28.6))$

Step 5

Multiply $- 1$ by $- 10$ .

$- 10 \ln (15.3) + 10 \ln (28.6)$
