$00.0025 = 2.5 \times {10}^{- 3}$

#### 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 $a \times {10}^{n}$, where $1 \le a < 10$ and $n$ is an integer.

This way $00.0025$ can be written as $2.5 \times {10}^{- 3}$.
