[1/1 Formula]
    Work: Calculate the value of equation -(350/650)*log(2,350/650)-(150/650)*log(2,150/650)-(150/650)*log(2,150/650) .
    Question type: Mathematical calculation
    Solution:
          -(350/650)*log(2,350/650)-(150/650)*log(2,150/650)-(150/650)*log(2,150/650)
        =-0.538462*log(2,350/650)-(150/650)*log(2,150/650)-(150/650)*log(2,150/650)
        =-0.538462*(-0.893084)-(150/650)*log(2,150/650)-(150/650)*log(2,150/650)
        =-0.538462*(-0.893084)-0.230769*log(2,150/650)-(150/650)*log(2,150/650)
        =-0.538462*(-0.893084)-0.230769*(-2.115479)-(150/650)*log(2,150/650)
        =-0.538462*(-0.893084)-0.230769*(-2.115479)-0.230769*log(2,150/650)
        =-0.538462*(-0.893084)-0.230769*(-2.115479)-0.230769*(-2.115479)
        =0.480892-0.230769*(-2.115479)-0.230769*(-2.115479)
        =0.480892-(-0.488187)-0.230769*(-2.115479)
        =0.480892--0.488187-(-0.488187)
        =0.969079-(-0.488187)
        =1.457266

    Answer:-(350/650)*log(2,350/650)-(150/650)*log(2,150/650)-(150/650)*log(2,150/650)=1.457266
