Question

7- square root of 3i

Answer 1

Answer: its the first two and the last one

Step-by-step explanation: not the third one

Answer 2

Step-by-step explanation:

Any complex number is of the form: $a + bi$ where a is real part and B is imaginary part.

Therefore, in given complex number: $7- \sqrt {3}i$

7 is real part.

$\sqrt {3}$ is imaginary part.

Hence, first two options are correct.

Last two options are incorrect because of the following reasons:

$- \sqrt {3}$ is coefficient of $i$ & not $7- \sqrt {3}$

Given number is a difference of a real number and imaginary number & not a sum of a real number and imaginary number.
