A number in scientific notation form with an exponent of zero has a value __________.

Explanation:
In scientific notation, a number is written as a × 10^n where the mantissa a is kept between 1 and 10 (not including 10). If the exponent is zero, 10^0 equals 1, so the value is just the mantissa a. Since a lies between 1 and 10, the overall value falls in that same range. Therefore, the number is between 1 and 10. While 1 is possible when the mantissa is exactly 1, the general result is the interval from 1 up to just under 10.
