The letter i in mathematics represents √-1. So, keep in mind. i = √-1.
Let's factor √-32 with the i in mind.
√-32 = √(32 * -1) = √32 * √-1 = √32i.
Just remember this formula: √-x = i√x

Answer:
25, 9
Step-by-step explanation:
(p . q)(8) means do q first to 8 then do p to that, which is the same as writing p(q(8)). Then just plug the numbers in.
q(8)=√8+8=√16=4
p(4)=4^2+9=16+9=25
The second one is the opposite order but same reasoning.
p(8)=8^2+9=64+9=73
q(73)=√73+8=√81=9
