The real part of the given number is $3$ $3$ and its imaginary part is $- 5$ $-5$ .

The standard form of a complex number is $a + i b$ $a+ib$ .
Where $a$ $a$ is the real part and $b$ $b$ is the imaginary part.

Write the given complex number in the standard form
The standard form of $- 5 i + 3 = 3 - i 5 = 3 + i (- 5)$ $-5i+3=3-i5=3+i(-5)$ .

Therefore the real part of the given number is $3$ $3$ and its imaginary part is $- 5$ $-5$ .
