Question

Show the expanded notation for 2c + 5c.7c(c + c) + (c + c + c + c + c)2 + c + 5 + c2 + 2 + 5 + 5 + 5 + 5 + 5

Answer 1

The expanded notation of an expression can be found by writing each term representing a product as a sum.

The term 2c means "two times c". Then, its expanded notation is:

`c+c`

Also, the term 5c means "five times c". Then, its expanded form is:

`c+c+c+c+c`

Therefore, the expanded notation for 2c + 5c is obtained by adding the above two expanded notations:

`(c+c)+(c+c+c+c+c)`
