What is the leading coefficient and degree in these two problems?

Question

1). 4x^3y - 3xy^2 + x^2y^3

2). -x^5y + 2x^2y^2 + xy^4

Answer 1

You have to specify degree in x, or degree in y. In the first, in x it is degree 3 with a leading coefficent of 4. In y it is degree 3, with leading coefficnet 1.

On the second, it is degree 5 in x, leading coefficnet -1, but in y, it is degree 4, leading coefficent 1.
