Respuesta :
A complex number is a number of the form a + bi, where i = and a and b are real numbers. For example, 5 + 3i, - + 4i, 4.2 - 12i, and - - i are all complex numbers. a is called the real part of the complex number and bi is called the imaginary part of the complex number.
Real part of the complex number [tex]-5 + 3i[/tex] is -5.
What is complex number?
" Complex numbers are such numbers which expressed in form of [tex]a+ i b[/tex], where 'a' represents the real part and b represents the imaginary part containing [tex]i[/tex] . Value of [tex]i = \sqrt{-1}[/tex]."
According to the question,
Given complex number,
[tex]-5 + 3i[/tex]
Compare it with general form of complex number [tex]a+ i b[/tex] we get,
Real value of( [tex]-5+ 3i[/tex]) = -5
Imaginary value of [tex]-5+ 3i[/tex] = 3
Hence, real part of the complex number [tex]-5 + 3i[/tex] is -5.
