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.
  • The default taken for h is Max.
  • form can be a product of terms.
  • Exponent works whether or not expr is explicitly given in expanded form.
  • Exponent[expr, {form1, form2, ...}] gives the list of exponents for each of the formi.
