Question 47810
.


It is absolutely inappropriate way to communicate with the tutors by posting 
4 (four) different Math problems in one post.


The rules of this forum (and the rules of any other similar forum) require 
ONE and ONLY ONE problem per post.


Why such rules are established ? - - - Due to two reasons.


First reason is the requirement of polite communication.
When you place more than one problem per post, you demonstrate disrespect to tutors.


Second reason is that when you place many assignments in one post, the result is a mess, 
which is difficult to write and difficult to read.



Simply separate your post in 4 (four) different posts, and you will get
perfect solutions with detailed and complete explanations !



Always be polite with the tutors - and happiness will be yours !
