Algebra.Com's Answer #82093 by josmiceli(19441)![]() ![]() You can put this solution on YOUR website! This infinite series is just another way of saying \n" ); document.write( " \n" ); document.write( "problem, they just pulled out each \n" ); document.write( " \n" ); document.write( "Believe it or not, \n" ); document.write( "You find it with a little trick. \n" ); document.write( "First call the repeating decimal \n" ); document.write( "Then show what \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "subtract \n" ); document.write( "decimal points cancel out. I'm left with \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "OK, what if you had \n" ); document.write( "What's the value? Use the same trick a little differently \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "now subtract \n" ); document.write( " \n" ); document.write( " |
