Question

What is the degree of the given monomial $7y$?

(A). 0
(B). 1
(C). 2
(D). 7

Answer 1

Hint: The degree of the monomial is found by finding the sum of the exponents of the variables used in the monomial. The given monomial is $7({{y}^{1}})$ . Here we have only one variable y which has an exponent of 1. Thus, the degree here is 1.

Complete step-by-step answer:
The degree of a monomial is defined as the sum of the exponents of the variables used in the monomial.
In algebra, a monomial is an expression that contains only one term. In other words, a monomial is a polynomial with a single term. Generally, monomials include numbers, variables, or a number and a variable multiplied together, two or more variables multiplied together. A monomial is an expression that does not contain any arithmetic operators.
The given monomial here is $7({{y}^{1}})$ . Therefore, here we have one variable y which has an exponent of 1.
The degree is found to be 1.
The answer is B. 1.

Note: We must note that the degree is found by the addition of the exponents of the variables in the polynomial. Here the given expression is a monomial meaning a polynomial with one term. Here the constant term is 7 and the variable that is multiplied along with it is y. Here y has an exponent of 1. Thus, the degree is 1 as the sum of exponents of the variables is 1. We must look closely at the exponents and add them to get the correct solution of the degree.
