<p>say if a question just says "abc=1", can "a", "b", and "c" be the same number?
What's the rule on that?</p>
<p>Of course. if ABC= 1, then A=1 b=1 and c=1 .</p>
<p>They can also be different since 1/a=bc . Thus BC can be reciprocals of each other.</p>
<p>A=1 b=5/1 and c=1/5
see?</p>
<p>Hope that answers your question.</p>
