Question

What is the degree of the polynomial −6x3y2 5x4−7z?

Answer 1

4

I also recommend writing the polynomial as -6x^3y^2 5x^4-7z as it was a bit confusing to tell which numbers were the exponents.

Answer 2

Answer:

5 is the highest degree.

Step-by-step explanation:

We are given the following polynomial:

$-6x^3y^2+5x^4-7z$

and we are to find the degree of this polynomial.

The degree of a polynomial is the highest degree of its monomials (which  are the individual terms in a polynomial) with coefficients that are greater than 0.

In the given polynomial, we have multiple variable term $-6x^3y^2$ and two single variable terms.

So we can find the highest degree by adding the exponents of  $-6x^3y^2$  i.e. 3+2=5.
