log3(x-1)=log9(x+5) 中log9(x+5) 怎么化简?

log3(x-1)=log9(x+5) 求x log3(x-1)=log9(x-5) 求x 方程log3 (x-1)=log9 (x+5) 解方程log3^(x-1)=log9^(x+5) log3(x-1)=log9(x+5)详细过程, log3(x-1)=log9(x+5) 中log9(x+5) 怎么化简? log3(x-1)=log9(x+5) 中log9(x+5) 怎么化简? 求满足等式log3^(x-1)=log9^(x+5)的x 填空题：方程log3(x-1)=log9(x+5)的解是____________ log3(x-1)=log9(x+5)怎么解?RT,3和9是底数.. 函数f（x）=log3（x-5）-log9（17-x）的零点是 由换底公式怎么得到log9(x+5)=log3[2（x+5)]=1/2log3(x+5)还有“0.4 方程log3(π-1)＝log9(x+5)的解是? log3(x2)+log9(1/x)+3/2=0怎么解 求x,y值.6log9^x+3log27^y=8log3^x+2log9^y=2 解log81(X)+log9(X)+log3(X) < 7/4 log9(x-5)+log9(x=+3)=1 9是那个log的底 log9(x+5）为什么可以化简为½log3 x+5?求解答!
