Answer:
266
Step-by-step explanation:
Don't give more points. We work for a great deal less. Thank you for what you have given.
The complex conjugate of 16 + i√10
is
16 - i√10 Notice the only difference is the minus sign.
(16 + i√10)(16 - i√10)
First: 16 * 16 = 256
Outside: - 16 * i√10
Inside: 16*i√10
Last: i*√10 * -i*√10 = - i^2 (√10)^2
i^2 = -1
(√10)^2 = 10
Last: + 10
Notice the outside and inside terms cancel and the last term becomes + 10
The answer is 256 + 10 = 266
