 Okay, let's try this significant figure question. Write the following number with the indicated amount of significant figures. So the number is seven, eight, five, two, uh, sorry, four, two, four. With seven, six, six. Well, this has only one, two, three, four, five, six figures in it. So what you would have to do is add a decimal point and a zero. But let's put them all in scientific notation. So with seven, six, six, remember always scientific notation, you're going to put the decimal point after the first number. So we got one, two, three, four, five, six. And since it says seven, we're going to have to add that zero on there. And then multiply that by ten times. Well, the decimal point originally is right there. So we go one, two, three, four, five. So that number is going to be seven point eight, five, four, two, four, zero times ten to the fifth. So let's do it with six significant figures. That original number has six figures. So all we've got to do is write that original number with the decimal point moved. And then, of course, again, it's just going to be times ten to the fifth. In fact, all of them will be times ten to the fifth. One, two, three, four, five times ten. Okay, so let's do it in five significant figures. So since this has six, we're just going to write the first five figures down. And watch out if this is bigger or less than five. So we'll either round up or down. Well, anyway, so we go seven point eight, five, four, two. Okay, so that's the first five figures. And we drop that four, and then multiply it by ten to the fifth, like that. So let's do it to four. Let's just look at this one. Just drop that two. Of course, that two isn't bigger than, isn't five or bigger. So it's just going to be seven point eight, five, four times ten to the fifth, like that. Three significant figures. Again, the four isn't bigger than or equal to five. So it's just going to be seven point eight, five times ten to the fifth. We're going to do it to two significant figures. Well, five is equal to five or greater than five. So we're going to round eight up. So it's going to be seven point nine times ten to the fifth. And then if we look at this number, nine is bigger than five. So the number is going to be eight times ten to the fifth. Okay? If you insisted on writing these in quote unquote decimal form instead of scientific notation or decimal notation, and you wanted to write this number out in significant figures of one, that would be eight, one, two, three, four, five. Right? Yep. So that would be the number. If you insisted. Okay? But I would not like this. Okay? I would like it. Does that make sense? Okay.
