From the expression 5x^23, we identify the terms as follows:
5 = <span>coefficient </span>x = <span>variable </span>23 = exponent x = base
The coefficient is the constant in the term, the variable is any letter in a term, the exponent is the the number of times a number is being multiplied by itself in a power and the base is <span>the number being multiplied in a power.</span>
