This question wants us to explain why scientific notation is used in economics.
00:06
So we're going to use 2004 debt, which is $7 ,379 ,000 ,000 ,000 ,000 ,000 ,000 ,000 million.
00:25
Then the u .s., so this is the debt, and then the u .s.
00:31
Population, which is 293 million, 7 ,000.
00:44
We're going to write this in scientific notation.
00:47
So in order to write scientific notation, we are going to move these decimals that they would have here over until we only have one number left.
00:59
So for our debt, one, two, three, four, five, six, seven, eight, nine, ten, eleven, twelve.
01:07
So for our debt, this would be one point three, three.
01:14
7, 9 times 10 raised to the 12th power.
01:21
And then for our population, we're going to do the same thing.
01:25
1, 2, 3, 4, 5, 6, 7, 8.
01:30
So this will be 2 .937 times 10 raised to the 8th power.
01:37
Putting it in standard notation just makes it easier to deal with the numbers.
01:42
You don't have to worry about all the zeros...
