Question

How many terms are there in the algebraic expression $5x+4y-20?$

• A. $2$
• B. $3$
• C. $4$
• D. $5$

Answer 1

The correct option is B $3$

$\underset{–}{\text{Term of an Algebraic Expression:}}$
Each part of an algebraic expression which is separated by plus $(+)$ or minus $(-)$ sign is called a term of an algebraic expression.

$\underset{–}{\text{Note:}}$
It’s important to remember that the division sign $(÷)$ or multiplication sign $(\times )$ does not separate the terms of an algebraic expression.
$\underset{–}{}$

We are given with the algebraic expression: $5x+4y-20$

In this expression, $5x$ is the first term, $4y$ is the second term and $20$ is the third term.

Therefore, we can say that there are $3$ terms in $5x+3y-20.$
Therefore, option (b.) is the correct answer.

$\underset{–}{\text{Note:}}$
In the third term $20$, there is no variable also we can say that the power of variable is $0$. This can be shown as:
$20=20a^0$, where $a$ is any variable.
