Algebra.Com's Answer #500462 by JulietG(1812)![]() ![]() You can put this solution on YOUR website! Not quite subtract as you have done, because it is the factors at the big end that are left. \n" ); document.write( "Write 14! as 14·13·12·11! and 10! as 10·9!: \n" ); document.write( "10·9!·11! \n" ); document.write( "---------------------------- \n" ); document.write( "9!·14·13·12·11!\r \n" ); document.write( "\n" ); document.write( "You can cancel and get: \n" ); document.write( "10 \n" ); document.write( "------------- \n" ); document.write( "14·13·12\r \n" ); document.write( "\n" ); document.write( "= 5/1092 \n" ); document.write( " |
