Question

The absolute value of the number z = 1-i is:

a) 1

b) sqrt(2)

c) 2

d) 0​

Answer 1

Answer:

option c is correct....

Answer 2

Answer:

The absolute value is b) sqrt(2).

Step-by-step explanation:

The given complex number is z = 1 - i, where 1 is the real part and -i is the imaginary part.

The absolute value is given by the square root of the sum of squares of the magnitudes of both parts.

$|z| = \sqrt{a^2 + b^2}$, where a=1 and b=-1

$|z| = \sqrt{1^2 + (-1)^2}$

$|z| = \sqrt{1+1}$

|z| = √2

Therefore, the absolute value of the number z=1-i is √2.
