There are infinitely many.Let x be any real number <=2 and let y = 4 - x then x + y = x + (4 - x) = 4. Since x is an arbitrary number, there are infinitely may choices for x and so infinitely many possible answers.
Also, for any x other than 0, let z = 4/x. Then x * z = x * (4/x) = 4. Again, since x is arbitrary number, there are infinitely may choices for x and so infinitely many possible answers.
Next, let s = any positive real number and let t = log(4)/log(s) [to any base]. Then, st = 4 and, since s is an arbitrary positive number, ...
