First ( 1-i ) = 2^1/2( cos(-pie/4) + i sin(-pie/4) )
Now its whole power x = 2
The modulus of the complex number inside the bracket = 1
To equality to exist its modulus should be same on both sides.
to get equal modulus the value of x should be 2.
But if it is two we can see that LHS is imaginary, so x can't be 2.
therefore no of integral solutions of is 0 ( zero )
