How do you find #abs( 3 - 2i)#? Precalculus Complex Numbers in Trigonometric Form Complex Number Plane 1 Answer Shwetank Mauria Mar 24, 2016 #|3-2i|=3.606# Explanation: Finding #|3-2i|# means finding the modulus of complex number #3-2i#. As modulus of a complex number #a+bi# is given by #sqrt(a^2+b^2)# #|3-2i|=sqrt(3^2+(-2)^2)=sqrt(9+4)=sqrt13=3.606# Answer link Related questions What is the complex number plane?
