Powers of 10 are useful in multiplying by decimals when dealing with large or small quantities, such as in scientific calculations or financial estimations. For example, if you need to calculate the total cost of multiple items priced in decimals (like $0.75 each) for a large quantity (like 1000 items), you can express the decimal as a power of 10 (0.75 = 7.5 x 10^-1) to simplify the multiplication process. This approach helps in quickly determining results while maintaining accuracy in calculations.

When multiplying do you move the decimal to the left or right?

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.

How is the world better from being freed from German and Japanese control?

The Axis powers exterminated people because of their religious beliefs, or because of the cloths they wore, or because of the life styles that they lived. The Axis powers also ENSLAVED people to support their conquests. This is why there would be NO NEGOTIATION with these men.
