WebbIn writing expressions for unknown quantities, we often use standard formulas. For example, the algebraic expression for "the distance if the rate is 50 miles per hour and the time is T hours" is D = 50 T (using the formula D = R T ). An expression like x n is called a power. Here x is the base, and n is the exponent. WebbThis number is usually written x^n. The number x is usually called the base of the expression x^n, and n is called the exponent.
