Find the degree of the polynomial

7a3b2 - 2a4 + 4b - 15

Degree

When ur polynomial has more then one variable ... and this one does ... the degree is the highest term degree

7a^3b^2 ... this term has a degree of 5

2a^4 ... this term has a degree of 4

4b ... this term has a degree of 1

15 ... this term has a degree of 0

so the highest degree term has a degree of 5 ... so that is the degree of this polynomial.

now if u just had 1 variable, the degree would be the highest exponent
