#2.56# x #10^9# is scientific notation, which when put into a calculator as 2.56 x 10^9 will be changed to its expanded form, which is #2,560,000,000#, unless the calculator has been set to scientific notation mode. Then you will have something like 2.56E9, which means #2.56# x #10^9#.

Scientific calculators usually have an [ee], [EE], or an [EXP] button, in which you enter the first part, 2.56, then press the exponent button and enter the exponent. Your calculator will show something like 2.56E9, and when you press [=], it will show the expanded form, unless it has been set to scientific notation mode.
