Please proof this:"The product of any two even integers is a multiple of 4."This is what I have so far:let n, m be even integers and let d be a integer that is divisible by 4.n=2k.m=2l.d=4p.such that k,l,p exists in Z (integers).n ⢠m = d2k ⢠2l = 4p2(kâ¢l)=4p. And now I don't know what to do next.Thanks
