In the expression a^b, which symbol represents the base?

Explanation:
The key idea here is naming the role of the parts in a power. In a^b, the base is the quantity that is being raised to a power, and the exponent is the power you raise it to. The first symbol (a) is the base because it’s the thing that’s going to be multiplied by itself b times. The word that matches that role is “base,” since it describes what the first symbol is doing in the expression. For example, in 3^4 the base is 3 and the exponent is 4. The other terms refer to different ideas—exponent names the amount of times, a coefficient is a multiplying factor in polynomials, and a variable is a placeholder—so the correct concept that names the part being raised is the base.
