Scientific notation in standard form

Take the number of the exponent and move the decimal that many places. If it is positive move it left and if it is negative move it right.

For Example:

2.57x10³ = 2570

Fill in any access spaces with zero.

Taking that same number to the negative 3 power

2.57x10^-3

0.00257

I put a 0. to show it is a distinctive decimal.
