Question

How do you evaluate `ln(6.4times3.8/10)`?

Answer 1

`ln(6.4xx3.8/10)=color(green)(0.8887139641)`

Explanation:

Method 1
Evaluate `(6.4xx3.8/10)=6.4xx0.38=2.432`
Use calculator to evaluate: `ln(2.432)=0.8887139641`

Method 2
Note that `ln(6.4xx3.8/10)=ln(6.4)+ln(3.8/10)=ln(6.4)+ln(0.38)`
Use calculator to evaluate: `ln(6.4)=color(white)("xxx")1.8562979904`
Use calculator to evaluate: `ln(0.38)=underline(-0.9675840263)`
Add natural log results: `color(white)("XXXXXXxXXX")0.8887139641`
