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 of a number just writes the significant digits followed by an appropriate power of ten. The most common form of scientific notation inserts a decimal point after the first significant digit, follows the significant digits with times, x, and then 10 to a power. If the original number is at least one, the power is the number of digits between the decimal point and the first number on the left.
