〖1/1算式〗
作业:求算式 √(100×(1+(14.65×0.78)^2)÷0.78^2÷(0.04*0.78^2+1)÷(0.25*0.78^2+1)÷((172.39*0.78)^2+1)) 的值.
题型:数学计算
解:
√(100×(1+(14.65×0.78)^2)÷0.78^2÷(0.04*0.78^2+1)÷(0.25*0.78^2+1)÷((172.39*0.78)^2+1))
=√(100×(1+11.427^2)÷0.78^2÷(0.04*0.78^2+1)÷(0.25*0.78^2+1)÷((172.39*0.78)^2+1))
=√(100×131.576329÷0.78^2÷(0.04*0.78^2+1)÷(0.25*0.78^2+1)÷((172.39*0.78)^2+1))
=√(100×131.576329÷0.78^2÷1.024336÷(0.25*0.78^2+1)÷((172.39*0.78)^2+1))
=√(100×131.576329÷0.78^2÷1.024336÷1.1521÷((172.39*0.78)^2+1))
=√(100×131.576329÷0.78^2÷1.024336÷1.1521÷(134.4642^2+1))
=√(100×131.576329÷0.78^2÷1.024336÷1.1521÷18081.621082)
=√1.013488
=1.006721 答案:√(100×(1+(14.65×0.78)^2)÷0.78^2÷(0.04*0.78^2+1)÷(0.25*0.78^2+1)÷((172.39*0.78)^2+1))=1.006721你的问题在这里没有得到解决?请到 热门难题 里面看看吧!
