Algebra.Com's Answer #87666 by MaxLiebling(13)![]() ![]() ![]() You can put this solution on YOUR website! Start with the given equation: \n" ); document.write( " \n" ); document.write( "add \n" ); document.write( " \n" ); document.write( "Note: logarithm is a strictly increasing function AND on both sides you have nothing but a Log(...) -> drop Log: \n" ); document.write( " \n" ); document.write( "add \n" ); document.write( " \n" ); document.write( "calculate left side: \n" ); document.write( " \n" ); document.write( "calculate right side: \n" ); document.write( " \n" ); document.write( "combine both sides: \n" ); document.write( " \n" ); document.write( "that is: \n" ); document.write( " \n" ); document.write( "divide both sides by 3: \n" ); document.write( " \n" ); document.write( "calculate \n" ); document.write( " \n" ); document.write( "proof left hand side: \n" ); document.write( " \n" ); document.write( "proof right hand side: \n" ); document.write( " \n" ); document.write( "both sides are equal: |
