Question

What is the degree of monomial $5xy{z}^2$?

• A. $1$
• B. $4$
• C. $5$
• D. $3$

Answer 1

The correct option is B $4$

The degree of a monomial is the sum of the exponents of all of its variables.

In $5xy{z}^2$, we have $3$ variables namely $x,y$ and $z$.

Exponent of $x$ in $5xy{z}^2$ is $1$.
Exponent of $y$ in $5xy{z}^2$ is $1$.
Exponent of $z$ in $5xy{z}^2$ is $2$.

Degree of the monomial $5xy{z}^2$ $=1+1+2$
$=4$

The degree of the monomial $5xy{z}^2$ is $4$. Therefore, option (b.) is the correct answer.
