Answer:
- The simplified expression is:

- The simplified expression is undefined for m=3
Explanation:
The given expression is:

The numerator can be siplified by using factorization and denominator will be simplified using the formula

So,

A fraction is undefined when the denominator is zero. In order to find the value of m on which the simplified fraction will be undefined we will put denominator equal to zero.
So,

Hence,
- The simplified expression is:

- The simplified expression is undefined for m=3
Most managers see inappropriate dressing every day. Some are left angered while some are confused as to what is the right way to approach such situations. What follows next needs to be professional oriented. Being the manager, I would start by finding out what the appropriate dressing policies are. Some companies might have dress code policies while others might not. Assuming that this company has, I would read these policies carefully. The next thing that is required from me is to have a small conversation with the employee discretely. As professional as I can be, I will mention how I feel his or her dress code is inappropriate and try to summon the employee by asking him or her whether they are fully aware of the appropriate dress code. I will try to agree with the employee on what is appropriate and what is not. If we agree, requesting the employee to home and change clothes is unnecessary, but if the need to do that arises, I would consider that to be an option.

This situation takes place under the isolation condition of the user from the container's internal model. Abstract data types use iterators for the maintenance of the transversal of the data structure.
