A number to the power of negative one is equal to one over that number. For example, five to the negative one power equals one over five, or 1/5.
Know MoreThe negative exponent rule says that when doing calculations with negative exponents, any negative exponents in the top half of a fraction get moved to the bottom half and become positive exponents. This works for any negative power, not only the power of one. For example, to calculate five to the negative two power, first move the expression to the denominator and make it positive. This gives one over five to the positive two power, which is equal to 1/25.
The reverse is also true. Negative exponents in the denominator of a fraction get moved up to the numerator and become positive exponents.

Full Answer >The cube root of 54 is equal to 3.78. The cube root of a number, x, is equal to the number, y, such that y times y times y equals x. For the number 54, 3.78 times 3.78 times 3.78 is equal to 54.
Full Answer >Zero squared is still equal to zero because zero times any real number is zero. Squaring a number simply means to multiply it by itself, or to raise it to the exponent of two. For example, zero squared can be written as 0*0 or 0^{2}.
Full Answer >One cubic centimeter is equal to one milliliter, or a thousandth of a liter. This also means that a cube that is one cubic centimeter measures one centimeter on all of its sides (length, width and height).
