Work: Calculate the value of equation -8/13*log(2,8/13)-5/13*log(2,5/13) .
Question type: Mathematical calculation
Solution:
-8/13*log(2,8/13)-5/13*log(2,5/13)
=-8/13*(-0.700439)-5/13*log(2,5/13)
=-8/13*(-0.700439)-5/13*(-1.378513)
=-0.615385*(-0.700439)-5/13*(-1.378513)
=0.43104-5/13*(-1.378513)
=0.43104-0.384615*(-1.378513)
=0.43104-(-0.530197)
=0.961237
Answer:-8/13*log(2,8/13)-5/13*log(2,5/13)=0.961237
