Question

Just Checking my answers.....

Answer 1

What is the degree of the polynomial? 6ax^3 - 5ax + 9ab^3
A. 6
B. 4
C. 5
D. 3

Answer 2

I think it's B

Answer 3

Why do you think it's B?

Answer 4

The degree of a multivariable polynomial is equal to the largest sum of exponents In this case, the largest sum is 4 since the exponents for 6ax^3 and 9ab^3 are 1 and 3, which add to 4. So I think it's B.

Answer 5

No, those don't add to 4. x is the only changing variable in that polynomial (I assume); a and b are just constants, and even if you raise a constant to a constant power, it's still just a constant. So if you absorb each of the constants into one another when possible, you get:\[Cx^{3}-Cx +C\]
The largest exponent is 3, so the degree is 3.
