# How do you find abs( 2-3i )?

$| 2 - 3 i | = 3.606$
Finding $| 2 - 3 i |$ means finding the modulus of complex number $2 - 3 i$.
As modulus of a complex number $a + b i$ is given by $\sqrt{{a}^{2} + {b}^{2}}$
$| 2 - 3 i | = \sqrt{{2}^{2} + {\left(- 3\right)}^{2}} = \sqrt{4 + 9} = \sqrt{13} = 3.606$
