Answer 1

Answer:

Q.3.

Step-by-step explanation:

The degree of a polynomial is the highest of the degrees of its monomials with non-zero coefficients.

Degree of

first term =x5y6=5+6=11

Second term =−7x3y10=3+10=13

Third term =20x5y6z5=5+6+5=16

∴ the highest power is 16

∴ Degree of the polynomial=16
