Answer 2

Given,

The complex number (z) is = (-1-i)

To find,

The modulus of the given complex number.

Solution,

We can simply solve this mathematical problem by using the following mathematical process.

The general form of any complex number :

z = a+ib

Modulus of that complex number

|z| = √(a)²+(b)²

Here,

z = (-1-i)

Comparing with the general form of complex number,

a = -1

b = -1

Modulus of the complex number will be :

|z| = √(-1)²+(-1)² = √(1+1) = √2

Hence, the modulus of the given complex number is √2
