# What is the multiplicative inverse of complex numbers?

## What is the multiplicative inverse of complex numbers?

The multiplicative inverse of a complex number z is simply 1/z. It is denoted as: 1/z or z-1 (Inverse of z) It is also called as the reciprocal of a complex number and 1 is called the multiplicative identity.. For example: Let assume z = a+ib, then as per the property z.1 = z, its inverse is z = 1/z.

How do you find the additive inverse of a complex number?

Let Z = x + iy be the given complex number. Then its inverse is -Z = -x – iy. For example, the additive inverse of – i – 1 = – (- i – 1) = i + 1.

### What is additive and multiplicative?

Additive Identity and Multiplicative Identity are two different identity properties of numbers. When additive identity is added to a number, it returns the original number. Similarly, when multiplicative identity is multiplied by any number, it returns the original number.

What is the difference between additive and multiplicative relationships?

Additive relationships mean you add the SAME number to any x-value to get the corresponding y-value. Multiplicative relationships mean you multiply any x-value times the SAME number to get the corresponding y-value.

#### What is the additive identity of complex numbers?

0
For any set of numbers, that is, all integers, rational numbers, and complex numbers, the additive identity is 0. It is because when you add 0 to any number; it doesn’t change the number and keeps its identity.

How do you find the multiplicative inverse of z?

Note: Alternatively, we can also find the multiplicative inverse of any complex number z by using the direct formula of z−1=ˉz|z|2.

## What is difference between additive inverse and multiplicative inverse?

What is the difference between the additive identity and the multiplicative identity?

What is the Difference Between Additive Identity and Multiplicative Identity? Additive identity is used for addition operations whereas multiplicative identity is used for the multiplication operations. Additive identity is represented as x + 0 = x = 0 + x. Multiplicative identity is represented as p × 1 = p = 1 × p.
