What terminology do we use to describe the half in the expression one-half to the fifth power and the five in the expression one-half to the fifth power?

We begin by recalling that an expression of the form 𝑎 to the 𝑛th power is called an exponential expression or the 𝑛th power of 𝑎. We call 𝑎 the base of the expression and 𝑛 the exponent or power. In this question, we have the expression one-half to the fifth power. The one-half is the number that is being taken to a power, and the five is the power itself. We can therefore conclude that in the expression one-half to the fifth power, one-half is called the base of the expression and five is called the exponent of the expression.
