9,18,27,64,( ).
给定一组权值36,2,64,5,9,49,18,27,98,89构造一棵哈夫曼树
27,18,9,( ),0
18比27 64比0.8
18 27 64是数列吗
54×18+27×64如何巧算
1+9+18+27=?
把下列数化为最简分数10/6= 18/15= 36/27= 27/18= 18/6= 10/9= 50/45= 69/21= 64/14=tankyou
log(27)32 × log(64)27+log(9)2 × log(4)根号27=?log(27)32 × log(64)27+log(9)2 × log(4)根号27=?
2,4,8,16,( ),64和24,12,36,18,54,27,78,( )和5,7,5,9,5,11,5,( )和1,4,9,16,25,( ),49,64
9/27 16/64 25/100 21/63 35/45 18/81 28/42 88/99请把这些分数变成最简分数/=----
线性代数的问题四阶行列式,1,1,1,12,4,3,14,16,9,18,64,27,1则D=?
数字推理 157,64,27,8,9()
简算:(45×27×64)÷(15×9×8)
找规侓 1,1,4,8,9,27,16,64,25,(),()
27/64,( )/9,3/16,( )/8,1/12
(2/3)^x(9/8)^x=27/64
27又18/19÷9=
