Answer

Explanation:

Step1: Recall negative - exponent rule

A number in scientific notation (a\times10^{-n}) (where (1\leqslant a<10) and (n) is a positive integer) can be written in standard form by moving the decimal point (n) places to the left. Here (a = 7) and (n=9).

Step2: Move the decimal point

Starting with 7, move the decimal point 9 places to the left. We add 8 zeros before the 7. So (7\times10^{-9}=0.000000007).

Answer:

0.000000007
