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.

Step-by-step 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,  $7a^7 - 8a^7$

⇒ $7a^7 - 8a^7 = -a^7$
