# What is the order of the numbers from least to greatest?

## $A = 1.5 \times {10}^{3}$ $B = 1.4 \times {10}^{-} 1$ $C = 2 \times {10}^{3}$ $D = 1.4 \times {10}^{-} 2$

$D < B < A < C$

#### Explanation:

The first thing to look at is the $\times {10}^{x}$ part.

Comparing those, ${10}^{-} 2$ is the smallest, ${10}^{-} 1$ is the second smallest, and then we have the two ${10}^{3}$.

$A = 1.5 \times {10}^{3} \text{ }$ and $\text{ } C = 2 \times {10}^{3}$

Since $2 > 1.5$, we have that $C$ is larger than $A$.
