[1/1 Formula]
    Work: Calculate the value of equation 5×(log(221.25)-log(145.5))÷(log(290)-log(145.5)) .
    Question type: Mathematical calculation
    Solution:
          5×(log(221.25)-log(145.5))÷(log(290)-log(145.5))
        =5×(5.399293-log(145.5))÷(log(290)-log(145.5))
        =5×(5.399293-4.980176)÷(log(290)-log(145.5))
        =5×0.419117÷(log(290)-log(145.5))
        =5×0.419117÷(5.669881-log(145.5))
        =5×0.419117÷(5.669881-4.980176)
        =5×0.419117÷0.689705
        =2.095585÷0.689705
        =3.038379

    Answer:5×(log(221.25)-log(145.5))÷(log(290)-log(145.5))=3.038379
