〖1/1算式〗
作业:求算式 6*sqrt((0.4*7.3)^2+1)/(7.3*sqrt((0.2*7.3)^2+1)*sqrt((0.5*7.3)^2+1)*sqrt((0.008*7.3)^2+1)) 的值.
题型:数学计算
解:
6*sqrt((0.4*7.3)^2+1)/(7.3*sqrt((0.2*7.3)^2+1)*sqrt((0.5*7.3)^2+1)*sqrt((0.008*7.3)^2+1))
=6*sqrt(2.92^2+1)/(7.3*sqrt((0.2*7.3)^2+1)*sqrt((0.5*7.3)^2+1)*sqrt((0.008*7.3)^2+1))
=6*sqrt9.5264/(7.3*sqrt((0.2*7.3)^2+1)*sqrt((0.5*7.3)^2+1)*sqrt((0.008*7.3)^2+1))
=6*sqrt9.5264/(7.3*sqrt(1.46^2+1)*sqrt((0.5*7.3)^2+1)*sqrt((0.008*7.3)^2+1))
=6*sqrt9.5264/(7.3*sqrt3.1316*sqrt((0.5*7.3)^2+1)*sqrt((0.008*7.3)^2+1))
=6*sqrt9.5264/(7.3*sqrt3.1316*sqrt(3.65^2+1)*sqrt((0.008*7.3)^2+1))
=6*sqrt9.5264/(7.3*sqrt3.1316*sqrt14.3225*sqrt((0.008*7.3)^2+1))
=6*sqrt9.5264/(7.3*sqrt3.1316*sqrt14.3225*sqrt(0.0584^2+1))
=6*sqrt9.5264/(7.3*sqrt3.1316*sqrt14.3225*sqrt1.003411)
=6*sqrt9.5264/48.972797
=6*3.086487/48.972797
=18.518922/48.972797
=0.378147 答案:6*sqrt((0.4*7.3)^2+1)/(7.3*sqrt((0.2*7.3)^2+1)*sqrt((0.5*7.3)^2+1)*sqrt((0.008*7.3)^2+1))=0.378147你的问题在这里没有得到解决?请到 热门难题 里面看看吧!
