Multiplying Decimals by Powers of Ten (Part2)

The video tutorial explains how to multiply decimal numbers by powers of 10. It demonstrates the process by showing how multiplying 1.25 by 10^2 results in 125, and multiplying by 10^3 results in 1250. The general rule is to move the decimal point to the right as many places as the power of 10. If there are not enough digits, zeros are added as placeholders. Examples are provided to illustrate these concepts.

What happens to each digit in a number when it is multiplied by 10 to the power of 2?
