Which statement is true about the polynomial 5s^6t^2 + 6st^2 - 8s^6t^2 - 6t^7 after it has been fully simplified?

Given:

The polynomial is

To find:

The correct statement about the given polynomial.

Solution:

We have,

On combining like term, we get

Here, the terms are . So, the number of terms is 3.

The degree of the polynomial is the highest power of the variable or the product of the variables.

Powers of terms are 6+2=8, 1+9=10, 7.

Since the highest power of the product of the variable is 10, therefore, the degree of the polynomial is 10.

Hence the correct option is b.
