〖1/1算式〗
作业:求算式 6*sqrt((0.4*7.38)^2+1)/(7.38*sqrt((0.2*7.38)^2+1)*sqrt((0.5*7.38)^2+1)*sqrt((0.08*7.38)^2+1)) 的值.
题型:数学计算
解:
6*sqrt((0.4*7.38)^2+1)/(7.38*sqrt((0.2*7.38)^2+1)*sqrt((0.5*7.38)^2+1)*sqrt((0.08*7.38)^2+1))
=6*sqrt(2.952^2+1)/(7.38*sqrt((0.2*7.38)^2+1)*sqrt((0.5*7.38)^2+1)*sqrt((0.08*7.38)^2+1))
=6*sqrt9.714304/(7.38*sqrt((0.2*7.38)^2+1)*sqrt((0.5*7.38)^2+1)*sqrt((0.08*7.38)^2+1))
=6*sqrt9.714304/(7.38*sqrt(1.476^2+1)*sqrt((0.5*7.38)^2+1)*sqrt((0.08*7.38)^2+1))
=6*sqrt9.714304/(7.38*sqrt3.178576*sqrt((0.5*7.38)^2+1)*sqrt((0.08*7.38)^2+1))
=6*sqrt9.714304/(7.38*sqrt3.178576*sqrt(3.69^2+1)*sqrt((0.08*7.38)^2+1))
=6*sqrt9.714304/(7.38*sqrt3.178576*sqrt14.6161*sqrt((0.08*7.38)^2+1))
=6*sqrt9.714304/(7.38*sqrt3.178576*sqrt14.6161*sqrt(0.5904^2+1))
=6*sqrt9.714304/(7.38*sqrt3.178576*sqrt14.6161*sqrt1.348572)
=6*sqrt9.714304/58.415128
=6*3.116778/58.415128
=18.700668/58.415128
=0.320134 答案:6*sqrt((0.4*7.38)^2+1)/(7.38*sqrt((0.2*7.38)^2+1)*sqrt((0.5*7.38)^2+1)*sqrt((0.08*7.38)^2+1))=0.320134你的问题在这里没有得到解决?请到 热门难题 里面看看吧!
