Answer 1

3a^5 - (-a^5) = 3a^5 + a^5 = 4a^5

6a^7 - 2a^7 = 4a^7

-3a^5 - (-2a^5) = -3a^5 + 2a^5 = -a^5

7a^7 - 8a^7 = -a^7

Answer 2

Answer: The simplified of the given expression shown below.

Explanation:

Since, First expression,
`3a^5-(- a^5)`

We can write
`3a^5-(- a^5)`=
`3a^5+a^5` =
`4a^5`

Second expression,
`6a^7 - 2a^7`

⇒
`6a^7 - 2a^7= 4a^7`

Third expression
`-3a^5 - (-2a^5)`

⇒
`-3a^5 - (-2a^5)` =
`-3a^5 + 2a^5` =
`-a^5`

Fourth expression,
`7a^7 - 8a^7`

⇒
`7a^7 - 8a^7 = -a^7`
