Question

How do you write 75,488 in scientific notation?

Answer 1

`75488=7.5488xx10^4`

Explanation:

Scientific notation is generally used to write very small or vey large numbers.

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 `axx10^n`, where `1<=a<10` and `n` is an integer.

This way `75488` can be written as `7.5488xx10^4`.
