Question

abc + bca + cab is _________.

• A. a monomial
• B. a binomial
• C. a trinomial
• D. a polynomial

Answer 1

The correct option is A

a monomial

We know that,
$a\times b\times c=b\times c\times a=c\times a\times b=abc=bca=cab$

All the three terms are same.
So, they are like terms and can be added to get a single term.

$abc+bca+cab=3abc$ or $3bca$ or $3cba$
So, $abc+bca+cab$ is a monomial.
