Abstract: Objective: Stress, psychological distress and fatigue are frequently co-morbid experiences, but the nature of any temporal and/or causal relationships is unclear. This study examined possible mediators and moderators of the stress/psychological distress â fatigue relationship in a non-clinical sample.bstract: Objective: Stress, psychological distress and fatigue are frequently co-morbid experiences, but the nature of any temporal and/or causal relationships is unclear.

One of the properties of quantities with exponents is that numbers with exponents can be added and subtracted only when they have the same base and exponent. Since all numbers in scientific notation have the same base (10), we need only worry about the exponents.
Scientific notation is used to express very large or very small numbers. A number in scientific notation is written as the product of a number (integer or decimal) and a power of 10. This number is always 1 or more and less than 10. For example, there are approximately 6,000,000,000 humans on earth. This number could be written in scientific notation as 6x109. The number 6,000,000,000 is equivalent to 6*1,000,000,000. The number 1,000,000,000 is equivalent to 109 or 10*10*10*10*10*10*10*10*10.
