Log[base3]x+log[basex]3=10/3


Use the base-swapping formula 
on the second term on the left:



Let u = log3(x)



Multiply through by LCD = 3u

      3uČ + 3 = 10u

3uČ - 10u + 3 = 0

  (u-3)(3u-1) = 0

u-3=0;  3u-1=0
  u=3;    3u=1
           u=

Substitute u = log3(x)

log3(x) = 3;   log3(x) = 

  x = 33       x = 
                   
  x = 27        x =
