15,18,21,22,42,44,50,60这八个数平均分两组每一组乘积相同

15,18,21,22,42,44,50,60这八个数平均分两组每一组乘积相同
15*22*42*60=18*21*44*50

将15,18,21,22,42,44,50,60分成乘积相等的两组有两种分法 都要 把15,18,21,22,42,44,50,60,分成乘积4相等的两组. 15,18,21,22,42,44,50,60这八个数平均分两组每一组乘积相同 将15 18 21 22 42 44 50 60分成乘积相等的两组.(有两种分法) 15,18,21,22,42,44,50,60 分为个数相等的两组,使这两组数的乘积相等,应该怎15,18,21,22,42,44,50,60 分为个数相等的两组,使这两组数的乘积相等,应该怎么分 18×19+19×20+20×21+21×22/36×38+38×40+40×42+42×44 vba 建立一个二维数组如下:hz=[{1,6,37,38,39,40;2,11,37,41,42,43;3,16,38,41,44,45;4,21,39,42,44,46;5,26,40,43,45,46;7,12,37,47,48,49;8,17,38,47,50,51;9,22,39,48,50,52;10,27,40,49,51,52;13,18,41,47,53,54;14,23,42,48,53,55;15,28,43,49,54,55;1 与6互质的最小合数是,4,6,8,9,10,12,14,15,16,18,20,21,22,24,25,26,27,28,29,30,32,33,34,35,36,38,40,42,44,45,46,48,49,50,51,52,54,55,56,58,60```好象不权 1+2+3+4+5+6+7+8+9+10+11+12+13+14+15+16+17+18+19+20+21+22+23+24+25+26+27+28+29+30+31+32+33+34+35+36+37+38+39+40+41+42+43+44+45+46+47+48+49+50请问答案是多少 请教5道数量关系题(1) 12,6,6,9,(),45 A 12 B 15 C 18 D 21(2) 0,10,24,50,() A 64,110 B 80,122 C 64,120 D 49,111(3) 0,-1,2,(),82 A 13 B 15 C 17 D 19(4) 28,29,31,34,39,(),57 A 40 B 42 C 44 D 46(5) 11,22,33,45,() 在长方形中画一个最大的半圆,已知半圆面积是31.4平方厘米,求长方形面积.1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 1617 18 19 20 21 22 23 24 2526 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 数字排列组合1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 这些数字用11个组一组.能排多少组 用matlab拟合下面一组数据的曲线x=[1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 7 android编程 数组:static final int g[][]=new int[][]{{3,16,29,42},{4,17,30,43},{5,18,31,44},{6,19,32,45},{7,20,33,46},{8,21,34,47},{9,22,35,48},{10,23,36,49},{11,24,37,50},{12,25,38,51},{13,26,39,52},{14,27,40,53},{15,28,41,54},};int a = new Ran 寻找下列数字的规律1 10 13 25 44 6 33 1243 58 49 17 28 47 31 4514 38 30 21 50 64 56 3534 54 55 51 32 40 62 169 61 37 42 57 59 53 205 60 63 3 48 29 39 826 41 22 27 18 4 52 2311 19 36 24 46 7 15 2可以追加分数二 亲爱的高手们,//城市节点数目 #define N 30 //城市坐标 double C[N][2]={ {2,99},{4,50},{7,64},{13,40},{18,54},{18,40},{22,60},{24,42},{25,62},{25,38},{37,84},{41,94},{41,26},{44,35},{45,21},{54,67},{54,62},{58,35},{58,69},{62,32},{64,60}, .急鸡鸡鸡鸡鸡 (22 21:15:42)三角形周长怎么算 如何巧算:(38/37+42/41+44/43)/(19/37+21/41+22/43)
