Question

Find the real and imaginary part of the following complex number:
a:3+4i
b:-5+i​

Answer 1

Answer:

a. 3 is the real part and 4i is the imaginary part.

b. 5 is the real part and i is the imaginary part.

Answer 2

$\huge\bf\boxed{\boxed{\underline{\red{Answer!!}}}}$

☞︎︎︎ $\mathrm\blue{3 + 4i}$

☞︎︎︎ $\mathrm\blue{- 5 + i}$

A complex Number has two a real part and imaginary part .

${\green{\overline{\green{\underline{\blue{\boxed{\orange{\mathtt{Complex Number = (real part) + (Imaginary part ) i}}}}}}}}}$

➪ $\mathrm\pink{3 + 4i}$

➪ So 3 is the real part

➪ And 4 is the Imaginary part

☞︎︎︎ $\mathrm\purple{- 5 + i}$

☞︎︎︎ $\mathrm\purple{- 5 + i = - 5 + 0i }$

☞︎︎︎ So - 5 is real part

☞︎︎︎ And 0 is the Imaginary part

More information :

* Complex Number is denoted by z :

eg : z = 2 + 2i

Let z = a + bi and

* So here a is real number = Re (z) = a

* And Imaginary part is b = Im ( z) = b

i can never appear as imaginary part ;

So :

Im(z) = 0 = z is the real number

Re(z) = 0 = z is the purly imaginary Number
