Answer:
(i)(a - 2y) (3x - 4b)
(iii) (m - n)(m + 4)
Step-by-step explanation:
(i)
3ax - 6xy + 8by - 4ab
= 3x (a - 2y) - 4b (-2y + a)
= 3x (a - 2y) - 4b (a - 2y)
= (a - 2y) (3x - 4b)
(iii)
![{m}^{2} - mn + 4m - 4n \\ \\ = m(m - n) + 4(m - n) \\ \\ = (m - n)(m + 4)](https://tex.z-dn.net/?f=%20%7Bm%7D%5E%7B2%7D%20%20-%20mn%20%2B%204m%20-%204n%20%5C%5C%20%20%5C%5C%20%20%3D%20m%28m%20-%20n%29%20%2B%204%28m%20-%20n%29%20%5C%5C%20%20%5C%5C%20%20%3D%20%28m%20-%20n%29%28m%20%2B%204%29)

Answer: Irrational</h3>
We cannot write sqrt(12) as a fraction of two whole numbers
Note how sqrt(12) = 3.464 and the decimal portion goes on forever without any known pattern (and it doesnt repeat either).
Compare this to something like sqrt(16) = 4 which can be written as a fraction 4/1, so sqrt(16) is rational
