So we have 160 billion here, which is a ginormous number, and we have to convert it into scientific notation.
00:06
So we have the follow format a times 10 to the b, where b must be an integer and a must be a number between 1 and 10.
00:12
So clearly 160 billion is greater than 10.
00:15
So in order to convert to this form, let's move the decimal point towards the left by 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 spaces.
00:30
And so we get 1 .6 times 10.
00:37
And we raise 10 to a power that will give us back this value, 160 billion...
