作业:求算式 0.33*(10*(0.109+2.661*ln3.1))+0.34*(10*(9.436+1.624*ln0.03))+0.32*(10*(5.453+1.694*ln2.91)) 的值.
题型:数学计算
解:
0.33*(10*(0.109+2.661*ln3.1))+0.34*(10*(9.436+1.624*ln0.03))+0.32*(10*(5.453+1.694*ln2.91))
=0.33*(10*3.119661)+0.34*(10*(9.436+1.624*ln0.03))+0.32*(10*(5.453+1.694*ln2.91))
=0.33*31.19661+0.34*(10*(9.436+1.624*ln0.03))+0.32*(10*(5.453+1.694*ln2.91))
=0.33*31.19661+0.34*(10*3.74135)+0.32*(10*(5.453+1.694*ln2.91))
=0.33*31.19661+0.34*37.4135+0.32*(10*(5.453+1.694*ln2.91))
=0.33*31.19661+0.34*37.4135+0.32*(10*7.262451)
=0.33*31.19661+0.34*37.4135+0.32*72.62451
=10.294881+0.34*37.4135+0.32*72.62451
=10.294881+12.72059+0.32*72.62451
=10.294881+12.72059+23.239843
=23.015471+23.239843
=46.255314 答案:0.33*(10*(0.109+2.661*ln3.1))+0.34*(10*(9.436+1.624*ln0.03))+0.32*(10*(5.453+1.694*ln2.91))=46.255314你的问题在这里没有得到解决?请到 热门难题 里面看看吧!
