A number in scientific notation form with a negative exponent has a value __________.

Explanation:
Numbers written in scientific notation take the form a × 10^n, where the mantissa a is between 1 and 10 and the exponent n is an integer. If n is negative, you’re dividing a by 10^|n|, which makes the value smaller than 1. For example, 4.5 × 10^-2 equals 0.045. Because the exponent is negative, the magnitude is less than 1.
