You can put this solution on YOUR website!
Let f(x) = 3x.
Find f(3)
Sub 3 for x
f(3) = 3*3 = 9
-----
f(1/3)
Sub 1/3 for x
---------------
and
Solve the equation 1296 x = 6
x = 6/1296
x = 1/216
-------------
last but not least
Simplify the expression.
3 log 3 (6x – 4)
If you mean
3%2Alog%283%2C%286x-4%29%29
= log%283%2C%286x-4%29%5E3%29
Not much simpler, if any.
