Question 891810
<pre>
log (base 3) x + log (base 5) 4x = 2

{{{log (3, (x)) + log (5, (4x)) = 2}}}

The way @JOSG did this problem, is not correct, in my opinion. This problem shouldn't be done with a calculator, especially
performing calculations from the beginning. As a matter of fact, I do believe that the answer should be EXACT.

I solved it and got the EXACT value of x to be: {{{highlight(matrix(1,4, 3^matrix(2,1, " ", log (15,   (25/4))), "=", "2.103176,", approximately))}}}. This doesn't seem to coincide with his final answer.
You can do the CHECK!!</pre>
