5 xx 10^7

Explanation:

Scientific notation is a way of writing very big or very numbers using powers of 10.

The powers of 10 are: 10," "100," "1000," "10000 ... etc

100 = 10^2" and 100,000 = 10^5 and so on.

400 means there are 4 hundreds, or
400 = 4 xx 100 = 4 xx 10^2
435 means there is a bit more than 4 hundreds, or

4.35 xx100 = 4.35xx 10^2

There is always only ONE digit before the decimal point.

5color(red)(0,000,000.) = 5 xx10^color(red)(7)

Count how many place holders there are.

5color(red)(1,300,000.) would be written as 5.35 xx 10^color(red)(7)
