Okay, here we have this:
Considering the provided expressions, we are going evaluate in the given values, so we obtain the following:
(a) Ipl when p = 13
Ipl
=|13|
=13
Here we obtain that Ipl when p = 13 is equal to 13.
(b) -lq| when q = -38
-Iql
=-|-38|
=-38
Here we obtain that -lq| when q = -38 is equal to -38.
