Question

If x- iy =√ a- ib prove that x+iy = √a +ib​

Answer 1

Answer:

$x - iy \: = \sqrt{a - ib} \\ taking \: conjugate \: on \: both \: side \\ x + iy \: = \sqrt{a + ib}$

hence proved

Answer 2

Answer:

Answer:

\begin{gathered}x - iy \: = \sqrt{a - ib} \\ taking \: conjugate \: on \: both \: side \\ x + iy \: = \sqrt{a + ib}\end{gathered}

x−iy=

a−ib

takingconjugateonbothside

x+iy=

a+ib

hence proved
