作业:求算式 0.34*(10*(9.436+1.624*ln0.01))+0.32*(10*(5.453+1.694*ln0.53))+0.33*(10*(0.109+2.661*ln4.3)) 的值.
题型:数学计算
解:
0.34*(10*(9.436+1.624*ln0.01))+0.32*(10*(5.453+1.694*ln0.53))+0.33*(10*(0.109+2.661*ln4.3))
=0.34*(10*1.957204)+0.32*(10*(5.453+1.694*ln0.53))+0.33*(10*(0.109+2.661*ln4.3))
=0.34*19.57204+0.32*(10*(5.453+1.694*ln0.53))+0.33*(10*(0.109+2.661*ln4.3))
=0.34*19.57204+0.32*(10*4.377517)+0.33*(10*(0.109+2.661*ln4.3))
=0.34*19.57204+0.32*43.77517+0.33*(10*(0.109+2.661*ln4.3))
=0.34*19.57204+0.32*43.77517+0.33*(10*3.990375)
=0.34*19.57204+0.32*43.77517+0.33*39.90375
=6.654494+0.32*43.77517+0.33*39.90375
=6.654494+14.008054+0.33*39.90375
=6.654494+14.008054+13.168238
=20.662548+13.168238
=33.830786 答案:0.34*(10*(9.436+1.624*ln0.01))+0.32*(10*(5.453+1.694*ln0.53))+0.33*(10*(0.109+2.661*ln4.3))=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!
