Explanation:

Step1: Move decimal point

Move the decimal point to the right until there is only one non - zero digit to the left of the decimal point. For 0.000456, we move the decimal point 4 places to the right to get 4.56.

Step2: Determine power of 10

Since we moved the decimal point 4 places to the right, the exponent of 10 is - 4. In scientific notation, a number is written as $a\times10^{n}$, where $1\leqslant|a|\lt10$ and $n$ is an integer.

Answer:

$4.56\times10^{-4}$
