Answer 2

Answer:

18p^2q^2r  -  270pqrn

Step-by-step explanation:

Using rainbow method, you have to multiply the expression outside bracket with each expression inside bracket like distributive method, you will get

 (9pqr x 2pq) - (9pqr x 30n)

=(18p^2q^2r)  -  (270pqrn)

Further simplification is not possible because squares are unlike terms.
