To find : The square root of the expression ?

Solution :

To find the square root of 1+4\sqrt{3}i

We can write the expression as

1+4\sqrt{3}i=(2)^2+(\sqrt3i)^2+2\times 2\times \sqrt3i

The RHS form an identity, a^2+b^2+2ab=(a+b)^2

1+4\sqrt{3}i=(2+ \sqrt3i)^2

Taking root both side,

\sqrt{1+4\sqrt{3}i}=2+\sqrt3i

Therefore, \sqrt{1+4\sqrt{3}i}=2+\sqrt3i
