Answer
$7,200$
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 $n=3$.
Thus, move the decimal point 3 places to the right to obtain:
$(7.2)(10^3)=7,200$
