hey i have more problems that can really exercise the mind! here are 3.(adsbygoogle = window.adsbygoogle || []).push({});

1. prove if q is divisible by (r +s) then either q is divisible by r or q is divisible by s.

2. if d>0, (fd+ed) = d(f,e). proof.

3. a divisible by b => a^m divisible by b^m a,b,m are in Z+.

i think i have some thoughts and i will share.

1. say that (b+c) = ma, where m is in Z+. after that, i am guessing...

2. could use contradiction here. say that d=0, then show the proof? anyone has any takes on this?

3. there exist m and n s.t. bn=ma. lost after here.

anyone w/ information/thoughts please share.
