When multiplying by a power of ten the digits of the number move left the same number of place value columns as the power.
When dividing by a power of ten the digits of the number move right the same number of place value columns as the power.
As this is awkward to do with pencil and paper, the effect on the position of the decimal point is used instead:
To multiply by a power of ten the decimal point is moved right the same number of digits as the power of 10;
To divide by a power of ten the decimal point is moved left the same number of digits as the power of 10;
If there are insufficient digits to do the moving zeros (0) are inserted as necessary.

∙ 8y agoYou move the decimal point to the right or to the left, as many digits as the power indicates. Example:3 multiplied by 10 to the power 3 = 3000. Note that the decimal point is implied in this case (to the right of each number). Also note that the decimal point has been moved three positions to the right, since the power of 10 has been three.

∙ 8y agoIf the power of ten is a positive integer n, then move the decimal point n places to the right, inserting trailing zeros as required. Whereas, if the power of ten is a negative integer n, then move the decimal point n places to the left, inserting leading zeros as required
