Work: Calculate the value of equation -(500/1000)*log(2,500/1000)-(300/1000)*log(2,300/1000)-(200/1000)*log(2,200/1000) .
Question type: Mathematical calculation
Solution:
-(500/1000)*log(2,500/1000)-(300/1000)*log(2,300/1000)-(200/1000)*log(2,200/1000)
=-0.5*log(2,500/1000)-(300/1000)*log(2,300/1000)-(200/1000)*log(2,200/1000)
=-0.5*(-1)-(300/1000)*log(2,300/1000)-(200/1000)*log(2,200/1000)
=-0.5*(-1)-0.3*log(2,300/1000)-(200/1000)*log(2,200/1000)
=-0.5*(-1)-0.3*(-1.736966)-(200/1000)*log(2,200/1000)
=-0.5*(-1)-0.3*(-1.736966)-0.2*log(2,200/1000)
=-0.5*(-1)-0.3*(-1.736966)-0.2*(-2.321928)
=0.5-0.3*(-1.736966)-0.2*(-2.321928)
=0.5-(-0.52109)-0.2*(-2.321928)
=0.5--0.52109-(-0.464386)
=1.02109-(-0.464386)
=1.485476
Answer:-(500/1000)*log(2,500/1000)-(300/1000)*log(2,300/1000)-(200/1000)*log(2,200/1000)=1.485476
