1, exponent is a parameter in power operation, for example, in the n-th power of a, a is the base and n is the exponent.

2. The degree refers to the degree of a single item, or the degree of a polynomial, that is, the sum of all letter indexes of a single item, or the highest degree of all single items in a polynomial. For example, in the monomial, 3 times the quadratic power of x, and the degree is 2; Polynomial, the quadratic power of 3 x, plus 8 x, the highest single degree is 2, then the polynomial degree is 2.
