Question

Find the imaginary part of
( 3+2√-54)^1/2-(3-2√-54)^1/2
​

Answer 1

$\sqrt{ - 54} \: is \: the \: imaginary \: part \:$

This is so because there is no real number having a negative square.

54 is square of some decimal value, here the the sign of the decimal value does not matter because even though it is negative it will give the answer in positive after squaring it.
