Exponent

Exponent[expr, form] gives the maximum power with which form appears in the expanded form of expr.

Exponent[expr, form, h] applies h to the set of exponents with which form appears in expr.

Example: Exponent[x^2 + a x^3, x] .

The default taken for h is Max.

Example: Exponent[x^2 + a x^3, x, List] .

form can be a product of terms.

Exponent works whether or not expr is explicitly given in expanded form.

Exponent[0, x] is -Infinity.
