[1/1 Formula]
    Work: Calculate the value of equation 0.42×18^(-9/8)-18.71×18^(-7/12) .
    Question type: Mathematical calculation
    Solution:
          0.42×18^(-9/8)-18.71×18^(-7/12)
        =0.42×18^(-1.125)-18.71×18^(-7/12)
        =0.42×18^-1.125-18.71×18^(-0.583333)
        =0.42×0.038709577550761-18.71×18^(-0.583333)
        =0.42×0.038709577550761-18.71×0.185249960385607
        =0.016258-18.71×0.185249960385607
        =0.016258-3.466027
        =-3.449769

    Answer:0.42×18^(-9/8)-18.71×18^(-7/12)=-3.449769
