\( 22 \quad z=j \sqrt{5}-1 \) find \( z \)

To find \( z \), we can start by substituting \( z \) with the given expression. The equation is \( z = j \sqrt{5} - 1 \). Now, we can express \( j \) in terms of \( z \): \[ z + 1 = j \sqrt{5} \] To isolate \( j \), we divide both sides by \( \sqrt{5} \): \[ j = \frac{z + 1}{\sqrt{5}} \] Now you have \( j \) in terms of \( z \). If you need the numerical value of \( z \) or more specific information, we can always substitute \( j \) with a known value. If you have a specific value for \( j \) in mind, let me know, and I can assist further!
