Question 1182373
.


What is written in parts (a) and (b) ?



////////////



What is written there,  is  UNREADABLE,  since you use non-standard symbols.



May I give an advice to you:


<pre>
    Instead of posting many questions in one post, many of which are unreadable,

    you better change your strategy and post few questions, but write them accurately.


    Then you will learn and will get much more in response from us, the tutors.
