E - notation is scientific notation where E represents "times 10 to the power of". So 4.6E - 8 means $4.6\times10^{-8}$.

Step2: Recall standard form

Standard form of a number is $a\times 10^{n}$ where $1\leqslant|a|\lt10$ and $n$ is an integer. Here $a = 4.6$ and $n=-8$.

Answer:

$4.6\times10^{-8}$
