Final answer:
In scientific notation, numbers between 0 and 1 will have a negative exponent because the decimal point is moved to the right to convert them to a number between 1 and 10.
Step-by-step explanation:
When you write a number in between 0 and 1 in scientific notation, the exponent of the power of 10 will be negative. This is because to express such small numbers in scientific notation, the decimal point must be moved to the right to form a number that lies between 1 and 10, which means the exponent needs to reflect the number of places the decimal was moved. For example, 0.000028 would be written as 2.8 × 10-5. The exponent here is -5, which indicates the decimal was moved 5 places to the right to make a coefficient of 2.8.
