Answer

Explanation:

Step1: Rewrite numbers in standard form

$7.2\times10^{5}=720000$ and $3.5\times 10^{3}=3500$

Step2: Subtract defective units from total produced

$720000 - 3500=716500$

Step3: Convert result to scientific - notation

$716500 = 7.165\times10^{5}$

Answer:

$7.165\times 10^{5}$
