Solve for Z
Z=\frac{20}{A^{2}}
A\neq 0
Solve for A (complex solution)
A=-2\sqrt{5}Z^{-\frac{1}{2}}
A=2\sqrt{5}Z^{-\frac{1}{2}}\text{, }Z\neq 0
Solve for A
A=2\sqrt{\frac{5}{Z}}
A=-2\sqrt{\frac{5}{Z}}\text{, }Z>0

A^{2}Z=20
Multiply A and A to get A^{2}.
\frac{A^{2}Z}{A^{2}}=\frac{20}{A^{2}}
Divide both sides by A^{2}.
Z=\frac{20}{A^{2}}
Dividing by A^{2} undoes the multiplication by A^{2}.
