Answer:
0
4z^5
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.
0
2m
-2m + 2p
2.Select the correct difference.
-3z^ 5 - (-7z^ 5)
= 3z^5+7z^5
= 4z^5
