Appendix II LAWS of EXPONENTS The International Symbols Committee has adopted prefixes for denoting decimal
multiples of units. The National Bureau of Standards has followed the recommendations of this committee, and has
adopted the following list of prefixes:

To multiply like (with same base) exponential quantities, add the exponents. In the language of
algebra the rule is am x an = am+n
AII-1
To divide exponential quantities, subtract the exponents. In the language of algebra the rule is
*Generally used with electrical quantities.
To raise an exponential quantity to a power, multiply the exponents. In the language of algebra (xm)n
= xmn.
Any number (except zero) raised to the zero power is one. In the language of algebra xO = 1
Any base with a negative exponent is equal to 1 divided by the base with an equal positive
exponent. In the language of algebra x-a = 1/xa
To raise a product to a power, raise each factor of the product to that power.
AII-2
To find the nth root of an exponential quantity, divide the exponent by the index of the root. Thus,
the nth root of am = am/n.
