# How do you find the degree of #9x^4y^3 – 8x^6 + 4xy^3 + 7#?

##### 2 Answers

13x^5y^6-8x^6+7

#### Explanation:

9X^4 Y^3 and 4XY^3 have both the same letters so you add both the bases which are the 9 and the 4 which is: 13, then you add up the amount of Xs in ONLY those two which is X^5, then you do the same to the Ys, you add them up and you should get: Y^6. now you check if you can add any thing else(you can't), so you are left with your remaining numbers which are: -8X^6+7 and you just add that to the end and you will get should: 13x^5y^6-8x^6+7.

See the explanation, below.

#### Explanation:

For a polynomial in two (or more) variables, the degree of each term (with non-0 coefficients) is the sum of the powers on the variables.

The degree of the polynomial is the greatest of the degrees of the terms (with non-0 coefficients).

So the degree of
