Answer

Explanation:

Step1: Recall negative - exponent rule

A number in scientific notation $a\times10^{-n}$ (where $1\leq a<10$ and $n$ is a positive integer) can be written in standard form by moving the decimal point $n$ places to the left. For $7\times 10^{-9}$, since $n = 9$, we start with 7.0 and move the decimal point 9 places to the left.

Step2: Write the number in standard form

We add 8 zeros between the decimal point and 7. So $7\times 10^{-9}=0.000000007$.

Answer:

0.000000007
