However, I'm assuming that you want to find the leading term and the degree of the polynomial correct?
First, we need to sort the terms of in descending exponential order. In other words, start with the term that has the largest exponent (which is ) and move onto , , etc
So the sorted polynomial is
Since the leading term is the first term on the left, this means that the leading term is .
Also, recall that the degree of a polynomial is simply the exponent of the leading term (ie it is the largest exponent).
Since the exponent of the leading term is 5, the degree is 5.
