Question 1151080: Given the equivalent impedance of a circuit can be calculated by the expression
𝑍=𝑍1*𝑍2/𝑍1+𝑍2
If 𝑍1=4𝑗+6 and 𝑍2=6−𝑗, calculate the impedance 𝑍 in both rectangular and polar forms.

You probably wanted (use parenthesis)




Z =  

= 

Multiply numerator and denominator by 12-3j:

= 

=  exact answer

=   to three decimal places



Polar form: left as an exercise.
