Answer:
Finding Information
You may assume, automatically, that academic text books are the primary source of information when you are engaged in a formal study programme. This may be true, to a degree, usually there is little need to question the credibility of such texts – they have probably been recommended by a tutor. There are, however, many other sources of information which should not be overlooked. Such sources include: the internet, newspapers, journals, transcripts from radio or TV programmes, leaflets, photographs and other artefacts (man-made objects).
Within the category of books there are many different types and genres, for example: fiction and non-fiction, including dictionaries, encyclopaedias, biographies, almanacs, archives, yearbooks and atlases, to name just a few. There are even more categories of websites and other internet resources. All sources of information can be of relevance depending on the subject matter of the research or project you’re working on.
It is important to understand that all information will have a certain degree of validity or otherwise. A document can be easily forged or altered, especially on the internet where anybody can publish anything. It is therefore necessary to use judgement when deciding which documents to use in the context of your study.
495/256 is the answer of sum of all the numbers is 0 then cubes =3(abc)
you might get the hint from a³ +b³ +c³.-3(abc)
