2. Select the correct difference.

-3z 5 - (-7z 5)

0

4z^5

Step-by-step explanation:

We are asked to

Simplify m - {n - [p + (m + n - p) ]}.

For that we remove first internal bracket and then next in the same order.

= m - {n - [p + m + n - p]}. (by removing the inner bracket)

Now we simplify the term inside by cancelling p

= m - {n - [ m + n ]}. Next is multiply by - the term m+n.

= m-[n-m-n]. Now n cancels out.

=m - (m) = 0

Finally we get 0 as answer.

2m

-2m + 2p

2. Select the correct difference.

-3z^ 5 - (-7z^ 5)

= 3z^5+7z^5

= 4z^5
