Work: Calculate the value of equation -9/14*lg(9/14)-5/14*(lg5/14) .
Question type: Mathematical calculation
Solution:
-9/14*lg(9/14)-5/14*(lg5/14)
=-9/14*lg0.642857-5/14*(lg5/14)
=-9/14*lg0.642857-5/14*0.049926
=-9/14*-0.191886-5/14*0.049926
=-0.642857*(-0.191886)-5/14*0.049926
=0.123355-5/14*0.049926
=0.123355-0.357143*0.049926
=0.123355-0.017831
=0.105524
Answer:-9/14*lg(9/14)-5/14*(lg5/14)=0.105524
