Algebra.Com's Answer #204393 by subudear(62)![]() ![]() ![]() You can put this solution on YOUR website! Given that 5+ln(8x)=23 -2lnx\r \n" ); document.write( "\n" ); document.write( "Lets simplify this\r \n" ); document.write( "\n" ); document.write( "ln(8x) + 2ln(x) = 23 - 5 \n" ); document.write( "ln(8x) + ln(x)^2 = 18 \n" ); document.write( "ln(8x*x^2) = 18\r \n" ); document.write( "\n" ); document.write( "ln(2x)^3 = 18\r \n" ); document.write( "\n" ); document.write( "3ln(2x) = 18\r \n" ); document.write( "\n" ); document.write( "ln(2x) = 6\r \n" ); document.write( "\n" ); document.write( "2x = e^6\r \n" ); document.write( "\n" ); document.write( "x = (e^6)/2\r \n" ); document.write( "\n" ); document.write( "I hope this clarifies your doubt. \n" ); document.write( " |
