Or does the product have to be EQUAL to 10? \n" ); document.write( "And by \"numbers\" do you mean integers? or can they be any numbers? \n" ); document.write( "------------------------------------------------------ \n" ); document.write( "Tell your lecturer that \"...is a maximum 10\" is not good English if what he means is that the product is anything less than 10. \n" ); document.write( "If \"numbers\" means integers, then there are only a small number of possibilities, and they are easy to check; there is clearly only one solution: 8 and 1. \n" ); document.write( "If the numbers are integers, the problem then seems of little value, since you don't learn anything from solving it. \n" ); document.write( "Since the problem apparently asks to find one solution, 8 and 1 is certainly the simplest answer (and the only answer, if the numbers are integers). \n" ); document.write( "A more useful problem -- that would teach the student something about problem solving -- would be to find the complete solution set of values for x that make the product x(9-x)^2 less than or equal to 10. \n" ); document.write( " \n" ); document.write( " |
