Question

How do you find the degree of the polynomial `7x ^ { 3} y ^ { 2} + 8x ^ { 4} y - 6x ^ { 4} y ^ { 2} + 7x ^ { 2} y`?

Answer 1

6

Explanation:

The degree of a polynomial is the maximum degree of its terms;

The degree of `7x^3y^2` is `3+2=5`

The degree of `8x^4y` is `4+1=5`

The degree of `-6x^4y^2` is `4+2=color(red)6`

The degree of `7x^2y` is `2+1=3`

Then the answer is 6
