What is the multiplicative identity of the complex number 4 + 8i

Mathematics
1 answer:
atroni [7]2 years ago
5 0

Answer:

1

Step-by-step explanation:

when you multiply an complex number by its multiplicatuive identity, in case 4+8i, you would multiply both the top and the bottom by 4-8i which is actually the value one since we cannot actually change the whole value of the number. By multiplying it by 1 and we get the same value without the imaginary number

(sorry if this doesn't make sense but I hope it helps)

about that did you forget to put -4 + 8i just to make sure about it because I am not sure if you forget it or not just making sure

MO bisects angle LMN, angel LMO = 6x-20.angle NMO= 2x+32 find angle LMN?
ICE Princess25 [194]
If MO bisects angle LMN:
6 x - 20 = 2 x + 36
6 x - 2 x = 36 + 20
4 x = 56
x = 56 : 4
x = 14
∠ LMN = 2 · ( 2 · 14 + 36 ) = 2 · ( 28 + 36 ) = 2 · 64 = 128
Answer : C )  x = 14, ∠ LMN = 128
