Final answer:
Scientific notation expresses very small numbers using negative exponents, with the coefficient between 1 and 10, and the power of 10 indicates how many places the decimal moves.
Step-by-step explanation:
The subject of this question is scientific notation, which is a way of expressing very large or very small numbers. For small numbers with values less than 1, scientific notation uses negative exponents. This means that the number 10 is raised to a negative power. For example, 0.00041 could be written in scientific notation as 4.1 × 10-4. The digit term, or coefficient, here is 4.1, and it must be a number between 1 and 10. The exponent term is the power of 10, which in this case is -4, indicating the decimal has moved four places to the left.
