It seems you're asking about two examples of scientific notation.

It's always of the form m * 10a, where m is real number and a is integer.

It's quite easy to convert that form to traditional notation - just write down the m number and move the decimal point a spaces left when a is bigger than 0 or right, when a is negative(adding zeros when necessary at the empty positions).

Examples:

2.4 * 102 = 240.0 (notice decimal point moved two spaces right)

4.0 * 10-10 = 0.0000000004(notice decimal point moved 10 spaces to the left).
