two

In 2x ^ 2 + y, 2x ^ 2Y, a-5, a, - 5, the number of monomials is

There are three 2x ^ 2Y, a, - 5

-The coefficient of 2x ^ 2Y is (), which is a binomial of degree ()

The coefficient (- 2) is a binomial of degree (3)

If the third power of the monomial - 5x and the m power of Y are the ninth power monomials, then what is m

(- 5x) 3 power YM power
=9-3=m=6
