Question

How do you find the degree of `13-4ab+5a^3b`?

Answer 1

It's degree is 4.

Explanation:

For a polynomial with two variables.
Degree is defined as collective highest power of both variables.

In term `13` degree is `0`.
,and in term `- 4ab` degree is `2` as `1` degree of `a` and `1` of `b`.
,and finally the degree in term `5a^3b` is `3+1=4`.
Hence the degree of polynomial `5a^3b -4ab + 13` is 4
and its leading co-efficient is 5.
