Log2⒊log3⒋log4ⅹ=log9⒊求x的值

Log2⒊log3⒋log4ⅹ=log9⒊求x的值 log5[log2(log9/log3)]=? 若log2^3×log3^4×log4^x=log9^3 ,求x （log2 3+log4 27）*（log3 4+log9 8）=log2的2是下标,后同 (log3,4+log9,4)log4,3—log2,2根号2 这怎么解答了 log2 根号2+log9 27+4^log4 13=? [log2(3)+log4(9)][log3(4)+log9(2)]等于注意：log2的2是下标,后同 (log4＾3+log8＾3)(log3＾2+log9＾2)+log2＾(32)的1/4次方 求(log2幂数3 +log4幂数3)(log3幂数2 +log9幂数4) 若log2[log3(log4)]=0,求x 利用换底公式求值：1.log2 25 ×log3 4 ×log5 9 2.（log4 3+log8 3）（log3 2+log9 2） 【（log4）^3+.（log8）^3】【.（log3）^2+.（log9）^2】=几啊 (log4 3+log8 3)(log3 5+log9 5)(log5 2+log25 2)= [log4(3)/log4(8)][log3(2)log9(2)]括号里是真数= = 我写错了 [log4（3）+log8（3）][log3（2）+log9（2）] log2^(log3^x)=log3^(log4^y)=0则x+y= 已知log2[log3(log4x)]=log3[log4(log2y)]=0,求x+y 已知log2(log3(log4x))=log3(log4(log2y))=0,求x+y的值 已知:log2[log3(log4x)]=log3[log4（log2y)]=0 求x+y的值
