Okay, let's write all of these decimals as scientific notation.
00:04
The first one is 7 .2 times 10, and let's move the decimal 1, 2, 4, 5, 6, 7 times, so to the negative 7th power.
00:15
The second decimal will be 2 .3, and it will be times 10 to the 1, 2, 3, move the decimal 4 times, so the negative 4th power.
00:27
On the bottom, we'll do 1 .8 times 10, and we've got to move that decimal.
00:32
Decimal, oh boy, one, two, three, four, five, six, seven, eight times.
00:38
So the negative eighth power.
00:40
Let me just count to make sure one more time.
00:42
One, two, three, four, five, six, seven.
00:48
It might be seven times.
00:49
One more time...
