To evaluate an expression means to find its numerical value. A power consists of a base and an exponent. According to the order of operations, operations inside parentheses (or other grouping symbols) are performed first, followed by the evaluation of powers ... then (*/) and (+-).
A literal factor is a factor in an algebraic expression that consists of a single variable or a combination of variables raised to a positive integer power. For example, in the expression 3xy^2, the literal factors are x and y.
