Question

What is the real part of the complex number -3+9i

Answer 1

The real part of given complex number -3 + 9i is -3

Solution:

We have to find the real part of complex number -3 + 9i

A Complex Number is a combination of real Number and an imaginary Number

The general form of complex number is:

a + bi

Where "a" and "b" are real numbers and i is the unit imaginary number

The given complex number is:

-3 + 9i

On comparing the above complex number with general form of complex number we get,

Real part = -3

Thus real part of given complex number is -3
