# How do you write 0.025 in scientific notation?

Mar 17, 2018

$2.5 \times {10}^{-} 2$

#### Explanation:

To write a number in scientific notation, we can write as follows:

$a \times {10}^{n}$, where $0 < a < 10$ and n is an integer.

In this question, the most probable value of $a$ would be $2.5$.

$2.5 = 0.025 \times 100$

Therefore,
$0.025$

$= 0.025 \times 100 \div i \mathrm{de} 100$

$= 2.5 \div i \mathrm{de} 100$

$= 2.5 \times {10}^{-} 2$

Note: $\frac{1}{10} ^ n = {10}^{-} n$
