2) с+с+с=1 с +1с +1с = (1 + 1+ 1)с =3с

Answer 2

1. а - а - а - a . a

To simplify this expression, we can combine the similar terms. Since all the terms involve the variable 'a,' we can rewrite the expression as:

a - a - a - a . a

Combining the similar terms, we get:

-3a . a

Simplifying further, we have:

-3a^2

So, the simplified expression is -3a^2.

2. c + c + c

Similarly, we can combine the similar terms:

3c

Therefore, the simplified expression is 3c.
