Thank you all for letting us know about the issue with the video explanation. I've sent a note to our content editors so that this can be fixed. However, since we have a very small team with lots to work, it may take a while for a new video explanation to be uploaded. In the meantime, here's a text explanation to accompany Mike's explanation in the video :)
We are asked to find the product of (10^4-10^2)(0.0012), where 0.0012 represents a repeating decimal. First, let's distribute the term (0.0012) across the first term:
Since the two terms have the same decimal value (0.1212...), when we carry out the subtraction, the decimal cancels out, leaving us with the difference, 12 (answer E).
Hi Jonathan! To watch the video, you'll need to remove the "https://" from the address bar in your browser, and replace it with "http://" (without the "s"). Then refresh the page, and the video should work! :)
