Answer:

#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#
