Question

Moving the decimal 4 spaces to the left will give a _________ exponent.

a. Positive
b. Negative

Answer 1

Moving the decimal 4 spaces to the left will give a negative exponent.

Step-by-step explanation:

When the decimal point is moved 4 spaces to the left, the resulting number will have a negative exponent. To see this, let's look at an example:

If we start with the number 0.0000567 and move the decimal point 4 spaces to the left, we get 0.00000567. In scientific notation, this would be written as 5.67 x 10-6. The negative exponent indicates that the number is less than 1.

Therefore, the correct answer is b. Negative.
