Question 193418
write the equation log 243 81 = 4/5 in exponential form.
{{{log(243,81) = 4/5}}}
That means that
{{{243^(4/5) = 81}}}
It's some big numbers, and a fractional exponent which makes it less clear.
I'll give some other examples:
{{{log(2,8) = 3}}}
The base is 2, so 2 is raised to some power.  That power is the exponent of 2 that gives 8, that is, 2^3 = 8.
So, the log of 8, base 2, is 3.
---------------------
 I do not understand. 
2) write the equation 6561 1/4 = 9 in logarthmic form 
The number is even bigger. But,
{{{9^4 = 6561}}}
--> {{{log(6561,9) = 1/4}}}
