# What is 10 to the power of negative 3?

A method for expressing powers as well as roots is known as an exponent. They have many applications in various fields of engineering, science and mathematics.

## Answer: 10 to the power of negative 3 is 0.001.

Let's see the solution step by step in detail.

**Explanation:**

Given: 10 to the power of -3 or 10^{(-3)}.

We know that according to a rule of exponent: a^{-b} = 1/a^{b}.

Hence, 10^{-3} = 1/10^{3} = 1/1000

And we know that 1/1000 = 0.001, according to the rules of fractions.
