Question 1133471
Log11 5 ÷ log11 15=? show solution without calculator
<pre>The answer by the other person is WRONG!!
{{{log (11, (5))/log (11, (15))}}}. Applying the CHANGE-OF-BASE rule, we get:
{{{(log ((5))/log ((11)))/(log ((15))/log ((11)))}}} ======> {{{matrix(1,11, log ((5))/log ((11)), "*", log ((11))/log ((15)), "======>", log ((5))/cross(log ((11))), "*", cross(log ((11)))/log ((15)), "=====>", log ((5))/log ((15)), "=", log (15, (5)))}}}
