Answer:
<em>c=6, d=2</em>
Step-by-step explanation:
<em>Equations </em>
We must find the values of c and d that make the below equation be true
Let's cube both sides of the equation:
The left side just simplifies the cubic root with the cube:
On the right side, we'll simplify the cubic root where possible and power what's outside of the root:
Simplifying
Equating the powers of x and y separately we find
c=6
5=3+d
d=2
The values are
To find the cofactor of
We cross out the Row and columns of the respective entries and find the determinant of the remaining matrix with the alternating signs.
Therefore in increasing order, we have;
