I need help with the bottom part I’m confused on how he got that answer? Ty!
baherus [9]

Answer:

The reason Carlos chose A as the correct answer is because by the way 4,325,000,000 is set up in standard form he would have it set back to 4.325 x 10^-9 instead of 4.325 x 10^9

√45 is the distance between which of the following complex numbers?
Schach [20]

Step-by-step explanation:

we don't see the complex numbers.

so, we cannot check their distances.

a suspicion, though.

sqrt(45) a distance between 2 complex numbers is

sqrt(a² + b²).

so,

a² + b² = 45

a nice combination of whole square numbers would be 6 and 3.

6² + 3² = 36 + 9 = 45

if that is the case, then that would mean one of the following committed numbers

6 + 3i

3 + 6i

-6 + 3i

6 - 3i

-6 - 3i

-3 + 6i

3 - 6i

-3 - 6i

one of these numbers must be the result of the subtraction of the 2 provided complex numbers.

remember

(a + bi) - (c + di) = a-c + (b-d)i
