Hich is true about the degree of the sum and difference of the polynomials 3x5y – 2x3y4 – 7xy3 and –8x5y 2x3y4 xy3? both the sum and difference have a degree of 6. both the sum and difference have a degree of 7. the sum has a degree of 6, but the difference has a degree of 7. the sum has a degree of 7, but the difference has a degree of 6.

The correct option is 3.

Step-by-step explanation:

The degree of a polynomial is the sum of the exponents of all the variables that appear in it.

The given expressions are

The sum of these expression is

The degree of sum is 6.

The difference of these expression is

The degree of difference is 7.

Since the sum has a degree of 6, but the difference has a degree of 7, therefore the correct option is 3.

207/8 is the right
