Given the following matrices:

$A=\left[\begin{array}{ccc}5& -2& 9\\ -7& -3& 8\\ 6& 4& 2\end{array}\right]$;$,B=\left[\begin{array}{ccc}2& -9& -7\\ -5& 8& 6\\ -2& 4& 8\end{array}\right]$

Determine:

$a=$ element by element division of $A$ by $B$

$b=3A^2-4B^3$

$c=$ the inverse of $BA$

$d=$ the transpose of $(A-B{)}^2$

$e=$determinant of $(AB{)}^2$

$f=A+B$ after replacing the elements of the $3^{rd}$ row of A and $2^{nd}$ column of $B$ with zeros
