作业:求算式 ((874*sqrt(2))^2+(2*3500+874*sqrt(2)-sqrt(3500^2+1500^2))^2-3500^2-1500^2)/(2*874*sqrt(2)*(2*3500+874*sqrt(2)-sqrt(3500^2+1500^2))) 的值.
题型:数学计算
解:
((874*sqrt(2))^2+(2*3500+874*sqrt(2)-sqrt(3500^2+1500^2))^2-3500^2-1500^2)/(2*874*sqrt(2)*(2*3500+874*sqrt(2)-sqrt(3500^2+1500^2)))
=((874*sqrt2)^2+(2*3500+874*sqrt(2)-sqrt(3500^2+1500^2))^2-3500^2-1500^2)/(2*874*sqrt(2)*(2*3500+874*sqrt(2)-sqrt(3500^2+1500^2)))
=(1236.023036^2+(2*3500+874*sqrt(2)-sqrt(3500^2+1500^2))^2-3500^2-1500^2)/(2*874*sqrt(2)*(2*3500+874*sqrt(2)-sqrt(3500^2+1500^2)))
=(1236.023036^2+(2*3500+874*sqrt2-sqrt(3500^2+1500^2))^2-3500^2-1500^2)/(2*874*sqrt(2)*(2*3500+874*sqrt(2)-sqrt(3500^2+1500^2)))
=(1236.023036^2+(2*3500+874*sqrt2-sqrt14500000)^2-3500^2-1500^2)/(2*874*sqrt(2)*(2*3500+874*sqrt(2)-sqrt(3500^2+1500^2)))
=(1236.023036^2+4428.136483^2-3500^2-1500^2)/(2*874*sqrt(2)*(2*3500+874*sqrt(2)-sqrt(3500^2+1500^2)))
=6636145.657598/(2*874*sqrt(2)*(2*3500+874*sqrt(2)-sqrt(3500^2+1500^2)))
=6636145.657598/(2*874*sqrt2*(2*3500+874*sqrt(2)-sqrt(3500^2+1500^2)))
=6636145.657598/(2*874*sqrt2*(2*3500+874*sqrt2-sqrt(3500^2+1500^2)))
=6636145.657598/(2*874*sqrt2*(2*3500+874*sqrt2-sqrt14500000))
=6636145.657598/(2*874*sqrt2*4428.136483)
=6636145.657598/10946557.39908
=0.606231 答案:((874*sqrt(2))^2+(2*3500+874*sqrt(2)-sqrt(3500^2+1500^2))^2-3500^2-1500^2)/(2*874*sqrt(2)*(2*3500+874*sqrt(2)-sqrt(3500^2+1500^2)))=0.606231你的问题在这里没有得到解决?请到 热门难题 里面看看吧!
