Remember the pythagorean theorem.
a^2 + b^2 = c^2
The complex number is a+bi, the absolute value is 'c'

Answer:
-3-i is the correct answer.
Step-by-step explanation:
Answer:
The factors of the polynomial are x = ± 
Step-by-step explanation:
consider x⁴ - 36 = 0
(x² - 6) (x² + 6) = 0
x² = 6 and x² = -6
∴ x = ±
The factors of the polynomial are x = ± 
43785 is not divisible by 2 because it's not an even number, and this also means it's not divisible by 10 because 10 = 2*5.
The sum of its digits is 4 + 3 + 7 + 8 + 5 = 27, which is divisible by 3 since 27 = 3*9, so 43785 is divisible by 3. We have 43785 = 3*14595.
It would be divisible by 9 if 14595 were also divisible by 3. That number has digital sum 1 + 4 + 5 + 9 + 5 = 24, which is divisible by 3, so 14595 is too and 14595 = 3*4865. So 43785 = 9*4865, and it is indeed divisible by 9.
14595 is clearly divisible by 5 because its ends with a 5.
