Guest cipher Posted May 18, 2004 Share Posted May 18, 2004 how do i show that |AB| = |A||B| ? Link to comment Share on other sites More sharing options...
jordan Posted May 18, 2004 Share Posted May 18, 2004 Well, in words it would be that since lABl equals the positive value of A times B, then lAl times lBl would be the same. The absolute value for both would be a positive number and since a positve times a positive is a positive, it would be the positive value of A times B. Don't know if that's what you're looking for, probably not. It's not really a mathematical proof, but it's what came to mind first. Link to comment Share on other sites More sharing options...
