Answer 2

Модуль числа -√5-2i равен 5.385164807134504.

Calculation:

To find the modulus of a complex number, we can use the formula:

|z| = √(Re(z)^2 + Im(z)^2)

In this case, the real part (Re) is -√5 and the imaginary part (Im) is -2. Plugging these values into the formula, we get:

|z| = √((-√5)^2 + (-2)^2) = √(5 + 4) = √9 = 3

Therefore, the modulus of -√5-2i is 3.
