Question

Find the multiplicative inverse of 2+3i/4+5i

Answer 1

Answer:

hey this is your answer..

Step-by-step explanation:

multiplicative inverse of z=z^-1

multicative inverse of z=1/z

putting z=2-3i

multicative inverse of 2-3i=1/2-3i

rationalising

=1/(2-3i) × (2+3i) / (2+3i)

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

using (a+b) (a-b)= a^2 -b^2

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