a superscript on a number that indicates how many times a number is to be multiplied by itself (for example, 34 = 3 × 3 × 3 × 3 = 81). In medical or scientific reports, powers of 10 are commonly used to indicate very large or very small numbers, such as in the examples 106 representing 1,000,000 or 10-6 representing 1/1,000,000. Exponents also are indicated by prefixes, such as mega- for 106 and micro- for 10-6.
In mathematics, the number that indicates the power to which another number is to be raised. It is written as a superscript (e.g., 102 or x2 indicates that 10 and x are to be squared, or multiplied by themselves). The exponent can have any numerical value and may be positive or negative; it does not have to be a whole number.
