Answer:e
Exponent of y is 1.
Step-by-step explanation:
We have been given the polynomial [tex]6xy^2-5x^2y? +9x^2[/tex]
Also it has been given that the degree of the polynomial is 3.
We know that the degree of a polynomial is highest exponent.
In case of more than one variables in a polynomial, we add the exponent of the variables of each term. The highest number must be the degree of the polynomial.
Now, since the degree of the polynomial is 3. Hence, the sum of the exponent of the variables x and y must be 3.
Mathematically, we can write
exponent of x + exponent of y = 3
2 + ? = 3
Subtract 2 to both sides
? = 1
Hence, the exponent of y is 1.
