The mean if the following set is 6
Answer:

Step-by-step explanation:
The given matrix equation is
![\frac{1}{2} \left[\begin{array}{cc}4&8\\x+3&-4\end{array}\right] -3\left[\begin{array}{cc}1&y+1\\-1&-2\end{array}\right]=\left[\begin{array}{cc}-1&-5\\7&4\end{array}\right]](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D4%268%5C%5Cx%2B3%26-4%5Cend%7Barray%7D%5Cright%5D%20-3%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D1%26y%2B1%5C%5C-1%26-2%5Cend%7Barray%7D%5Cright%5D%3D%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D-1%26-5%5C%5C7%264%5Cend%7Barray%7D%5Cright%5D)
We multiply the scalars to get;
![\left[\begin{array}{cc}2&4\\ \frac{x+3}{2}&-2\end{array}\right] --\left[\begin{array}{cc}3&3y+3\\-3&-6\end{array}\right]=\left[\begin{array}{cc}-1&-5\\7&4\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D2%264%5C%5C%20%5Cfrac%7Bx%2B3%7D%7B2%7D%26-2%5Cend%7Barray%7D%5Cright%5D%20--%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D3%263y%2B3%5C%5C-3%26-6%5Cend%7Barray%7D%5Cright%5D%3D%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D-1%26-5%5C%5C7%264%5Cend%7Barray%7D%5Cright%5D)
We simplify the right hand side to get;
![\left[\begin{array}{cc}-1&1-3y\\ \frac{x+3}{2}+3&4\end{array}\right] =\left[\begin{array}{cc}-1&-5\\7&4\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D-1%261-3y%5C%5C%20%5Cfrac%7Bx%2B3%7D%7B2%7D%2B3%264%5Cend%7Barray%7D%5Cright%5D%20%3D%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D-1%26-5%5C%5C7%264%5Cend%7Barray%7D%5Cright%5D)
The two matrices are equal. This means the corresponding entries are also equal.

Answer:
zⁿ = z³
Step-by-step explanation:
We have the expression:
√(z/ z^⅓)
Hence
= z^½/ (z^⅓)^½
= z^½/ (z^⅙)
= z^(½ ÷⅙)
= z ^(1/2 × 6/1)
= z³
Therefore: zⁿ = z³
