Answer
$0.000000314$
Work Step by Step
To convert a number in scientific notation, $a \times 10^{n}$, to standard decimal form:
(i) If $n$ is positive, move the decimal point $n$ places to the right; or
(ii) If $n$ is negative, move the decimal point $|n|$ places to the left.
The given scientific notation has $n=-7$.
Thus, move the decimal point 7 places to the left to obtain:
$(3.14)(10^{-7})=0.000000314$
