log9(log2(8)) = x ,求x

log9(log2(8)) = x ,求x 若log2^3×log3^4×log4^x=log9^3 ,求x Log2⒊log3⒋log4ⅹ=log9⒊求x的值 Log9(Log3(Log2^X))=0 外面的是大括号 怎么求 log2^3 x log9^5 x log25^8 log5[log2(log9/log3)]=? 求x,y值.6log9^x+3log27^y=8log3^x+2log9^y=2 log9(16) ×log2(27)=6步骤 log9 3+log9 27=怎么求~ (log2(3)+log8(9))x(log3(4)+log9(8)+log3(2)) 求log2分之根号2 8 log9 根号3 的值 求（log2^3+log8^9)(log3^4+log9^8+log3^2)的值 高中数学.快点哈log2的三次幂=a 求log9的八次幂? log3(x-1)=log9(x+5) 求x log3(x-1)=log9(x-5) 求x log4(log2^x)=log2(log4^x)求log2^x （log2 3+log4 27）*（log3 4+log9 8）=log2的2是下标,后同 log9^3+log2^1/25×log3^1/8×5^1/9=
