Algebra.Com's Answer #14522 by venugopalramana(3286)![]() ![]() You can put this solution on YOUR website! Let a not equal 0, b and c be integers with a and b relatively prime. \n" ); document.write( "Show that if a|b*c \n" ); document.write( "A|BC...HENCE.... \n" ); document.write( "BC=A*M......I.......WHERE M IS AN INTEGER \n" ); document.write( "AND B ARE RELATIVELY PRIME...THAT IS THEY HAVE NO COMMON FACTORS OR THEIR GCD IS 1. \n" ); document.write( "HENCE GCD =1 =AX+BY...WHERE X AND Y ARE INTEGERS..MULTIPLYING BY C THROUGHOUT,WE GET.. \n" ); document.write( "C=CAX+CBY...SUBSTITUTING EQN.I... \n" ); document.write( "C=CAX+AMY=A(CX+MY)=A*K SAY.....WHERE K=CX+MY... \n" ); document.write( "BUT C,X,M,Y ARE ALL INTEGERS...HENCE K IS AN INTEGER. \n" ); document.write( "C=A*K....OR...A DIVIDES C....A|C\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " then a|c. \n" ); document.write( "how do i give equations for relatively prime and divisible and then substitute. \n" ); document.write( "USE GCD OF A AND B =XA+YB...TO CONVERT INTO EQNS.HOPE YOU UNDERSTOOD.\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
