# How do you write 75,488 in scientific notation?

Apr 7, 2016

$75488 = 7.5488 \times {10}^{4}$
While writing in scientific notation, we use a single number consisting of a single digit in front of the decimal (at unit's place) and multiply it with an integer power (i.e. negative or positive) of $10$. Hence, it is of the form $a \times {10}^{n}$, where $1 \le a < 10$ and $n$ is an integer.
This way $75488$ can be written as $7.5488 \times {10}^{4}$.
