Answer 1

factors are numbers you multiply in order to get another number so in this equation there are 0. The answer would be c.

Answer 2

in \(a\times b\) there are 2 factors. here's a similar situation. (\(b=(q-1)^r\) .. one might argue there are \(r\) hidden factors hidden there but \(r+1\) is not in the options).
I would say 2.

Answer 3

Given an expression, the factors of an expression are other expressions which divide the expression "nicely". Here, p and (q-1) divide the expression "nicely". I agree with reemii on all of his comments.
