In this exercise we're being asked to write a very large number in scientific notation.
00:06
We are given 1 comma 2, 3, 4, comma 5, 00, comma, 0 ,000, this is 1 ,234 ,000, and i need to write it in scientific notation.
00:37
So the first thing i'm going to do is write all of the non -zero digits.
00:43
One, two, three, four, five, see what they did there.
00:49
And i'm going to put decimal right after the first digit.
00:53
So my value c, which is between one greater than or equal to one and less than 10, is going to be that 1 .2 .3.
01:13
Three, four, five, with the decimal right after the first digit.
01:20
And then i need to figure out what is the mal, what is the factor that's being multiplied to take it from 1 .2 to 1 billion, 234 million.
01:33
So one has to be multiplied by one billion, thousands, millions, billions, billions...
