Problem:                   Find the absolute value of the complex number: -8i

Step 1: Z = a + bi, a = 0 and b = -8

Solution Absolute value of the complex value = |Z| = √a² + b²

Step 2:                        

Solution |Z| = √a² + b² = √(0)² + (-4)² = √(0 + 64) = √64 = 8

Step 3:           

                                                             Step 3:                   The answer is:  8

 Complete
