Answer 1

The notation "2.976E–9" is already in scientific notation. It represents the number $2.976\times {10}^{-9}$.

In standard scientific notation, a number is expressed as $a\times {10}^n$, where $1\le a<10$ and $n$ is an integer. In this case, $a=2.976$ and $n=-9$. Thus, it is already correctly formatted.
