# How do you find abs( -2-i )?

$| - 2 - i | = 2.236$
Finding $| - 2 - i |$ means finding the modulus of complex number $- 2 - i$.
As modulus of a complex number $a + b i$ is given by $\sqrt{{a}^{2} + {b}^{2}}$
$| - 2 - i | = \sqrt{{\left(- 2\right)}^{2} + {\left(- 1\right)}^{2}} = \sqrt{4 + 1} = \sqrt{5} = 2.236$
