Answer:

Which is the degree of the polynomial 3x⁴y³-3x²y-5x-7?

A.2

b.4

c.6

d. 7

The degree of the polynomial is the highest exponent of the terms of the polynomial.

For example, 3x⁴y³-3x²y-5x-7 is a polynomial.

First, we need to add the exponents of every terms.

3x⁴y³ is the first term. The degrees are: 4 + 3 = 7

-3x²y is the second term. The degrees are 2 + 1 = 3

-5x is the third term. The degree is 1.

-7 is the last term. The degree is 0.

The highest degree is 7, wherein 3x⁴y³ is the leading term. Therefore, 7 is the degree of the polynomial 3x⁴y³-3x²y-5x-7.
