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 x0 = 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.
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.
