# What is the value of the product (3 – 2 i) (3 + 2 i)?

The sum of a real number and the imaginary number is called complex numbers. It is denoted by a + bi, where a is a real number and b is the imaginary part.

## Answer: The value of the product of (3 – 2 i ) (3 + 2 i ) is 13.

Let's multiply complex numbers.

**Explanation:**

The multiplication of complex numbers is a complex number.

To multiply (3 – 2 i) (3 + 2 i), we will use algebraic identity a^{2 }- b^{2 }= (a - b) (a + b)

⇒ (3 – 2 i) (3 + 2 i) = (3)^{2} - (2i)^{2}

⇒ 9 - 4 i^{2}

As we know that i^{2 }= - 1

⇒ 9 - 4 (- 1)

⇒ 9 + 4

⇒ 13
