    Work: Calculate the value of equation ((874*sqrt(2))^2+(2*2800+874*sqrt(2)-sqrt(2800^2+1500^2))^2-2800^2-1500^2)/(2*874*sqrt(2)*(2*2800+874*sqrt(2)-sqrt(2800^2+1500^2))) .
    Question type: Mathematical calculation
    Solution:
          ((874*sqrt(2))^2+(2*2800+874*sqrt(2)-sqrt(2800^2+1500^2))^2-2800^2-1500^2)/(2*874*sqrt(2)*(2*2800+874*sqrt(2)-sqrt(2800^2+1500^2)))
        =((874*sqrt2)^2+(2*2800+874*sqrt(2)-sqrt(2800^2+1500^2))^2-2800^2-1500^2)/(2*874*sqrt(2)*(2*2800+874*sqrt(2)-sqrt(2800^2+1500^2)))
        =(1236.023036^2+(2*2800+874*sqrt(2)-sqrt(2800^2+1500^2))^2-2800^2-1500^2)/(2*874*sqrt(2)*(2*2800+874*sqrt(2)-sqrt(2800^2+1500^2)))
        =(1236.023036^2+(2*2800+874*sqrt2-sqrt(2800^2+1500^2))^2-2800^2-1500^2)/(2*874*sqrt(2)*(2*2800+874*sqrt(2)-sqrt(2800^2+1500^2)))
        =(1236.023036^2+(2*2800+874*sqrt2-sqrt10090000)^2-2800^2-1500^2)/(2*874*sqrt(2)*(2*2800+874*sqrt(2)-sqrt(2800^2+1500^2)))
        =(1236.023036^2+3659.547001^2-2800^2-1500^2)/(2*874*sqrt(2)*(2*2800+874*sqrt(2)-sqrt(2800^2+1500^2)))
        =4830037.198051/(2*874*sqrt(2)*(2*2800+874*sqrt(2)-sqrt(2800^2+1500^2)))
        =4830037.198051/(2*874*sqrt2*(2*2800+874*sqrt(2)-sqrt(2800^2+1500^2)))
        =4830037.198051/(2*874*sqrt2*(2*2800+874*sqrt2-sqrt(2800^2+1500^2)))
        =4830037.198051/(2*874*sqrt2*(2*2800+874*sqrt2-sqrt10090000))
        =4830037.198051/(2*874*sqrt2*3659.547001)
        =4830037.198051/9046568.789121
        =0.533908
    Answer:((874*sqrt(2))^2+(2*2800+874*sqrt(2)-sqrt(2800^2+1500^2))^2-2800^2-1500^2)/(2*874*sqrt(2)*(2*2800+874*sqrt(2)-sqrt(2800^2+1500^2)))=0.533908
