Question

find the square root of i (iota)

Answer 1

hey friend this may help you

Answer 2

Answer:

$\sqrt{i}=\boxed{\frac{i+1}{\sqrt{2}}}$

Step-by-step explanation:

We know that:

$i = \sqrt{-1}$

$\implies i^2 = - 1$...............................(1)

$\bf{Lets\:find\:(i+1)^2\:\::-}$

$\implies ( i + 1 )^2 = (i + 1)(i + 1)$

$\implies (i + 1)^2 = i(i + 1) + 1(i+1)$

$\implies (i + 1)^2 = i^2 + i + i + 1$

$\implies (i + 1)^2 = -1 + 1 + 2 i$   [ From (1) ]

$\implies (i + 1)^2 = 2 i$

Taking square root both sides:-

$\implies i + 1 = \sqrt{2}\times\sqrt{i}$

$\implies \sqrt{i} = \frac{i + 1}{\sqrt{2}}$

Hope this helps you...............
