Real part of complex number Example-1

1. `A=5+6i`
Find Real part of complex number

Solution:
Here `A=5+6i`

For a complex number `z=a+bi`, the real part is `a` and the imaginary part is `b`.

So in complex number `A=5+6i`, the real part is `5` and the imaginary part is `6`

`:.` Re`(A)=5`

2. `A=-2+3i`
Find Real part of complex number

Solution:
Here `A=-2+3i`

For a complex number `z=a+bi`, the real part is `a` and the imaginary part is `b`.

So in complex number `A=-2+3i`, the real part is `-2` and the imaginary part is `3`

`:.` Re`(A)=-2`

3. `A=1-3i`
Find Real part of complex number

Solution:
Here `A=1-3i`

For a complex number `z=a+bi`, the real part is `a` and the imaginary part is `b`.

So in complex number `A=1-3i`, the real part is `1` and the imaginary part is `-3`

`:.` Re`(A)=1`
