(2 + 3i)^2 = 4 + 12i + 9(-1)
= 4 + 12i - 9
= -5 + 12i
(2 - 3i)^2 = 4 - 12i - 9(-1)
= 4 - 12i + 9
= 13 - 12i
REsult
= -5 + 12i + 13 - 12i
= 8 - 0i
Then
a = 8 and b = 0
The mixed number for 14/3 is 4 2/3
We want to find the number of dollars Chi makes for every hour he cuts lawns. This proportion would be dollars/hour.
329.12 / 34 = 9.68
Chi's hourly wage is $9.68 per hour.
Hope this helps!! :)
