# How do you write 6,160,000,000  in scientific notation?

$6.16 \cdot {10}^{9}$
In scientific notation, we basically remove powers or add powers of 10 to a number so that we can get in the form $a \cdot {10}^{b}$, where $b$ can must be a number so that $a$ is less than 10.
In this case, we can separate 6,160,000,000 like this: $6.16 \cdot 1000000000$, which we can represent as $6.16 \cdot {10}^{9}$
