[1/1 Formula]
    Work: Calculate the value of equation (10^(-7)*(66^2-5.52^2))/52+(10^(-10)*(66-5.52)*7.5)/0.8 .
    Question type: Mathematical calculation
    Solution:
          (10^(-7)*(66^2-5.52^2))/52+(10^(-10)*(66-5.52)*7.5)/0.8
        =(10^(-7)*(66^2-5.52^2))/52+(10^(-10)*(66-5.52)*7.5)/0.8
        =(10^-7*4325.5296)/52+(10^(-10)*(66-5.52)*7.5)/0.8
        =0.000433/52+(10^(-10)*(66-5.52)*7.5)/0.8
        =0.000433/52+(10^(-10)*(66-5.52)*7.5)/0.8
        =0.000433/52+(10^-10*60.48*7.5)/0.8
        =0.000433/52+0/0.8
        =0.000008+0/0.8
        =0.000008+0
        =0.000008

    Answer:(10^(-7)*(66^2-5.52^2))/52+(10^(-10)*(66-5.52)*7.5)/0.8=0.000008
