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
