3^x=15 (find x)
\n" ); document.write( ">x=log₃15
\n" ); document.write( ">x=log₃(3x5)
\n" ); document.write( ">x=log₃3 + log₃5
\n" ); document.write( ">x= 1 + log₃5
\n" ); document.write( "= 1 + (log(5)/log(3))
\n" ); document.write( "----------------------
\n" ); document.write( "Second line should be
\n" ); document.write( "x log3 = log 15 giving
\n" ); document.write( "x = log 15 / log 3 = 1.1770 / 0.4771
\n" ); document.write( "------------------
\n" ); document.write( "The result is the same, but Greenfinch's method is faster and simpler.
