I have a problem that I'm not aware of how to solve. I know about permutations and combinations, but...(adsbygoogle = window.adsbygoogle || []).push({});

Given that the possible values for a are all integers such that [tex]2 \leq a \leq m_{a}[/tex], and the possible values for b are all integers such that [tex]2 \leq b \leq m_{b}[/tex]; how many combinations of a and b give [tex]ab=x[/tex], when order matters (ab is counted seperately from ba)?

Could someone please help me out by explaining how this is solved or by providing an answer (preferably both, but whatever you could do would be greatly appreciated)?

Thank you very much for your help...
