Question

real and imaginary parts of4+2i/1-2i​

Answer 1

Answer:

real part is 0, imaginary part is 10i/3

Step-by-step explanation:

4+2i/1-2i

=4+2i/1-2i * 1+2i/1+2i

=4+2i(1+2i)/[1²-(2i)²]

=(4+8i+2i+4i²)/1+2

=[4+4(-1)+10i]/3

=[4-4+10i]/3

=0/3+10i/3

=0+10i/3

Answer 2

Step-by-step explanation:

a+ib ka "a" real part aur "b" imaginary part so 4+2i mein 4 real part aur 2 imaginary part hai aur 1-2i mei 1 real part aur 2 imaginary part
