a company manufactures electronic devices and has produced 7.2 x 10^5 units of a certain model. due to quality control issues, 3.5 x 10^3 units are deemed defective and need to be scrapped. how many units are fit for sale? express your answer in scientific notation.
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:
$7.165\times 10^{5}$
