Chapter 9, Problem 44P

(a)

To determine

Evaluate the complex number ${\left(4\angle 30°-10\angle 50°\right)}^{\frac{1}{2}}$ and express the answer in polar form.

(b)

To determine

Evaluate the complex number $\frac{1+j2}{6+j8-7\angle 15°}$ and express the answer in polar form.

(c)

To determine

Evaluate the complex number $\frac{{\left(3+j4\right)}^2}{12-j7+{\left(-6+j10\right)}^{\ast }}$ and express the answer in polar form.

(d)

To determine

Evaluate the complex number $\frac{{\left(3.6\angle -200°\right)}^{\frac{1}{2}}}{{\left(2.4\angle 45°\right)}^2{\left(-5+j8\right)}^{\ast }}$ and express the answer in polar form.
