Document Summary
A symbol, usually a letter, that represents one or more numbers. A mathematical phrase that includes one or more variables. A mathematical phrase involving numbers and operation symbols, but no variables. A power has two parts, a base and an exponent. To replace an expression with its simplest name or form. To substitute a given number for each variable, and then simplify. A number of such that a2=b. square root of b is the principle square root. Square root of b is the negative square root. The expression under the radical sign is the radicand. An expression made up of a radical symbol and a radicand. A subset of a set consists of elements from the given set. A real number that can be written as a ratio of two integers. Rational numbers in decimal form are terminating or repeating.
