〖1/1算式〗
作业:求算式 13.05*sqrt(1+(13.05/10)^2)*sqrt(1+(13.05/20)^2)*sqrt(1+13.05^2) 的值.
题型:数学计算
解:
13.05*sqrt(1+(13.05/10)^2)*sqrt(1+(13.05/20)^2)*sqrt(1+13.05^2)
=13.05*sqrt(1+1.305^2)*sqrt(1+(13.05/20)^2)*sqrt(1+13.05^2)
=13.05*sqrt2.703025*sqrt(1+(13.05/20)^2)*sqrt(1+13.05^2)
=13.05*sqrt2.703025*sqrt(1+0.6525^2)*sqrt(1+13.05^2)
=13.05*sqrt2.703025*sqrt1.425756*sqrt(1+13.05^2)
=13.05*sqrt2.703025*sqrt1.425756*sqrt171.3025
=13.05*1.644088*sqrt1.425756*sqrt171.3025
=13.05*1.644088*1.19405*sqrt171.3025
=13.05*1.644088*1.19405*13.088258
=21.455348*1.19405*13.088258
=25.618758*13.088258
=335.304914 答案:13.05*sqrt(1+(13.05/10)^2)*sqrt(1+(13.05/20)^2)*sqrt(1+13.05^2)=335.304914你的问题在这里没有得到解决?请到 热门难题 里面看看吧!
