## FAQs on NCERT Solutions Class 7 Maths Chapter 10 Algebraic Expressions

1. Choose the Correct Answer and Fill in the Blanks.

(2x – 7) is a _______________________ [ binomial / monomial ]

5x is a ____________________. [binomial/ monomial ]

3xyz is a ___________________. [ monomial/ trinomial]

A term of an expression having no literal factor is called a ______________ term.

An algebraic expression having only one term is called a _______________.

In –x, the coefficient of x is ________________.

- binomial
- monomial
- monomial
- constant
- monomial
- -1

2. Answer the Following Questions.

What do we call an expression having only one term?

What is the coefficient of x

^{3}in –x^{3}?What is the power of -3x

^{3}y?What is the value of -5x

^{2}at x = -1?

- monomial
- – 1
- 4
- – 5

3. How are Algebraic Expressions Formed? Illustrate with an Example.

An algebraic expression is formed by a combination of constants and variables, connected by the symbols +, —, x, and ÷. We can also obtain algebraic expressions by combining variables with themselves or with other variables.

E.g.: The expression x^{3} is obtained by multiplying the variable x by itself.

x* x * x = x^{3}

4. What are Like and Unlike Terms? Illustrate with an Example.

The terms having the same literal factors are called like terms (or similar terms) whereas the terms that do not have the same literal factors are called unlike terms (or dissimilar terms).

Example: In the expression 5x^{2}y + 3xy^{2} – xy -2xy^{2}, we have 5x^{2}y and –2yx^{2} are like terms.

The terms 3xy^{2} and – xy are unlike terms.

6. How do you identify like terms in an algebraic expression in algebraic expressions class 7?

In algebraic expressions class 7 like terms in an algebraic expression are terms that have the same variables raised to the same powers, even if their coefficients are different. For example, in the expression 3x+5y−2x+7y, the like terms are 3x and −2x as well as 5y and 7y. To combine like terms, you simply add or subtract their coefficients while keeping the variable part unchanged.
