Answer:

value of x is 9

Step-by-step explanation:

log_{3} x*(log_{3 } (x/3) +log_{3} (x/81)\\\\=log_{3} x(log_{3} x-log_{3} 3)+log_{3} x+log_{3} 81\\\\=(log_{3} x)^{2} -log_{3} x+log_{3} x-log_{3} 81\\\\=2log_{3} x-log_{3} 81=0\\\\=2log_{3} x=log_{3} 81\\\\=log_{3} x=\frac{1}{2} log_{3} 81\\\\                \\            =\frac{1}{2} log_{3} 3^{4} \\                                   (log_{a} a=1)\\                =2\\\\log_{3} x=2\\\\x=3^{2} =9

value of x is 9
