作业:求算式 0.33*(10*(0.109+2.661*ln4.3))+0.34*(10*(9.436+1.624*ln0.01))+0.32*(10*(5.453+1.694*ln0.53)) 的值.
题型:数学计算
解:
0.33*(10*(0.109+2.661*ln4.3))+0.34*(10*(9.436+1.624*ln0.01))+0.32*(10*(5.453+1.694*ln0.53))
=0.33*(10*3.990375)+0.34*(10*(9.436+1.624*ln0.01))+0.32*(10*(5.453+1.694*ln0.53))
=0.33*39.90375+0.34*(10*(9.436+1.624*ln0.01))+0.32*(10*(5.453+1.694*ln0.53))
=0.33*39.90375+0.34*(10*1.957204)+0.32*(10*(5.453+1.694*ln0.53))
=0.33*39.90375+0.34*19.57204+0.32*(10*(5.453+1.694*ln0.53))
=0.33*39.90375+0.34*19.57204+0.32*(10*4.377517)
=0.33*39.90375+0.34*19.57204+0.32*43.77517
=13.168238+0.34*19.57204+0.32*43.77517
=13.168238+6.654494+0.32*43.77517
=13.168238+6.654494+14.008054
=19.822732+14.008054
=33.830786 答案:0.33*(10*(0.109+2.661*ln4.3))+0.34*(10*(9.436+1.624*ln0.01))+0.32*(10*(5.453+1.694*ln0.53))=33.830786你的问题在这里没有得到解决?请到 热门难题 里面看看吧!
