You don't move the decimal point at all. You just multiply the numbers and the point should sort itself out or be put of how many digits it is to be.
0.10 = 1/10 so that multiplying by 0.10 is the same as dividing by 10.
The decimal point is moved to the left by the value of the power.

To the left of a decimal point are whole numbers. On the right of a decimal point are parts of a whole number.
When multiplying a decimal by a negative integer power of a number ( A ), the general rule is to move the decimal point to the left. Specifically, if you multiply by ( A^{-n} ) (where ( n ) is a positive integer), you divide the decimal by ( A^n ), effectively shifting the decimal point ( n ) places to the left. This results in a smaller value, as you are dividing by a power of ( A ).

0.10 = 1/10 so that multiplying by 0.10 is the same as dividing by 10.
Multiplying or dividing by ten.
It is because 0.10 = 1/10 and so multiplication by 0.10 is the same as division by 10, the opposite of multiplication by 10.
Multiplying a real number by a positive power of ten moves the decimal point that number (the exponent) of places to the right. Multiplying by a negative power of ten moves it to the left. For example, the -3 power of 10 is 1/1000; multiplying by that moves the decimal point 3 places to the left.
The decimal point is moved to the left by the value of the power.
two.
When multiplying, you move the decimal to the right. The number of places you move the decimal to the right is equal to the total number of decimal places in the numbers being multiplied. For example, if you are multiplying 2.5 by 3.2, you would move the decimal a total of three places to the right to get the final product.
Because that is how the decimal system is defined: the place value of each digit is ten times that of the digit to its right. Multiplication by 10 is equivalent to moving each digit to the its left or, equivalently, moving the decimal point to the right.
To the left of a decimal point are whole numbers. On the right of a decimal point are parts of a whole number.
Write the number out completely. Locate the decimal point. Move the decimal point left by one digit. You have multiplied the number by 0.1 Example: Multiply 293.56 by 0.1 Move decimal point left one position: 29.356
