PLEASE HELP!!!

When a whole number is multiplied by 10 to the power of 2, how does the placement of the decimal point change?


a) It moves two places to the right.

b) It moves ten places to the right.

c) It moves two places to the left.

d) It moves ten places to the left.

Answer 1

Answer: A) moves two places to the right

Example:

`2.567 * 10^2 = 2.567 * 100 = 256.7`

The positive exponent over the 10 tells us how many places to move to the right. If the exponent was negative, then we'd move to the left. This only works when the base is 10.
