It's 8pq

Unlike terms

See how the following expressions have been simplified:

p x q = pq (Note: we leave out the times sign).

3p x 2q = 6pq (Multiply the numbers first and then the letters).

p2 x q3 = p2 q3

5 x q = 5q



So ... 4p x 2q = 8pq

[factor-fiction]

Yes, the whole expression means :
4 x p x 2 x q

The convention is to write the simplified expression as 8pq but it would also be acceptable to write it as 8qp since the order of multiplication isn't relevant.

Is it coursework?
