Question 930024
<pre>
{{{log(3,(243))}}}{{{""=""}}}{{{x}}}

{{{3^x}}}{{{""=""}}}{{{243}}}


Since 3x3x3x3x3 = 243

{{{3^x}}}{{{""=""}}}{{{3^5}}}

Since the bases are the same on both sides and they are positive
and not equal to 1, so we can equate the exponents and disregard
the base.

So 

{{{x}}}{{{""=""}}}{{{5}}}

Therefore 

{{{log(3,(243))}}}{{{""=""}}}{{{5}}}
