[1/1 Formula]
    Work: Calculate the value of equation -(150/350)*log(2,150/350)-(150/350)*log(2,150/350)-(50/350)*log(2,50/350) .
    Question type: Mathematical calculation
    Solution:
          -(150/350)*log(2,150/350)-(150/350)*log(2,150/350)-(50/350)*log(2,50/350)
        =-0.428571*log(2,150/350)-(150/350)*log(2,150/350)-(50/350)*log(2,50/350)
        =-0.428571*(-1.222394)-(150/350)*log(2,150/350)-(50/350)*log(2,50/350)
        =-0.428571*(-1.222394)-0.428571*log(2,150/350)-(50/350)*log(2,50/350)
        =-0.428571*(-1.222394)-0.428571*(-1.222394)-(50/350)*log(2,50/350)
        =-0.428571*(-1.222394)-0.428571*(-1.222394)-0.142857*log(2,50/350)
        =-0.428571*(-1.222394)-0.428571*(-1.222394)-0.142857*(-2.807356)
        =0.523883-0.428571*(-1.222394)-0.142857*(-2.807356)
        =0.523883-(-0.523883)-0.142857*(-2.807356)
        =0.523883--0.523883-(-0.40105)
        =1.047766-(-0.40105)
        =1.448816

    Answer:-(150/350)*log(2,150/350)-(150/350)*log(2,150/350)-(50/350)*log(2,50/350)=1.448816
