Question

identify these as monominals, binominals and trinominals . 3xy, 3s+ 8y,23sdf -w+u

Answer 1

3xy is a monomial
3s+8y is a binomial
23sdf-w+u is a trinomial

Answer 2

Heya,

Monomial:-
Means a algebraic expression that consist of one/single term

Binomial:-
Means an algebraic expression that consists of dual/double/two terms

Trinomial:-
Means an algebraic expression that consists of three terms

So,
Answer of your question is,

3xy = Monomial term
3s + 8y = Binomial term
23sdf - w + u = Trinomial term

Hope my answer helps you :)
