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.
Convert 6,800,000,000 into scientific notation. We begin by writing our first few non-zero digits with a decimal point after the first digit. We get 6.8. Now, we count how many digits we have to move our beginning decimal point to get to the 6.8 spot.
