Step-by-step explanation:
Any complex number is of the form: [tex] a + bi[/tex] where a is real part and B is imaginary part.
Therefore, in given complex number: [tex] 7- \sqrt {3}i[/tex]
7 is real part.
[tex] \sqrt {3}[/tex] is imaginary part.
Hence, first two options are correct.
Last two options are incorrect because of the following reasons:
[tex] - \sqrt {3}[/tex] is coefficient of [tex]i[/tex] & not [tex] 7- \sqrt {3}[/tex]
Given number is a difference of a real number and imaginary number & not a sum of a real number and imaginary number.
