Question

evaluate. write your answer as a fraction or whole number without exponents. 10^{-3} =

Explanation:

Step1: Apply negative - exponent rule

The rule for a negative exponent $a^{-n}=\frac{1}{a^{n}}$. Here $a = 10$ and $n = 3$. So $10^{-3}=\frac{1}{10^{3}}$.

Step2: Calculate $10^{3}$

$10^{3}=10\times10\times10 = 1000$.

Step3: Get the final result

Since $10^{-3}=\frac{1}{10^{3}}$ and $10^{3}=1000$, then $10^{-3}=\frac{1}{1000}$.

Answer:

$\frac{1}{1000}$
