Algebra.Com's Answer #139126 by nerdybill(7384)![]() ![]() You can put this solution on YOUR website! \"log rules\" say: \n" ); document.write( "log a - log b = log a/b \n" ); document.write( ". \n" ); document.write( "Therefore, \n" ); document.write( "log (x+10)-log x \n" ); document.write( "= log ((x+10)/x) \n" ); document.write( ". \n" ); document.write( "It looks like of the choice given \n" ); document.write( "b) log x+10/x \n" ); document.write( "is the closest \n" ); document.write( "However, because of the the \"order of precedence\" it does NOT equal: \n" ); document.write( "log ((x+10)/x) \n" ); document.write( ". \n" ); document.write( "I would say your answer is: \n" ); document.write( "c) none of these \n" ); document.write( " |
