how to find the multiplicative inverse of 2-3i

  its multiplicative inverse =  1 / 2-3i

on both nr , dr v can multiply conjugate of 2 - 3i  = 2 + 3i 

= 1 * 2 +3i / 2-3i * 2+3i = 2+3i / 13 = 2/13 + (3/13)i 

thus its multiplicative inverse is 2/13 + (3/13)i 

hope u got it

multiplicative inverse of 2-3i= 1 / 2-3i * 2+3i / 2+3i

=2+3i / (2)2 - (3i)2

=2+3i / 4 - 9i2

=2+3i / 4+9 = 2+3i / 13
