Question

Which is an example of an algebraic expression?

a) O4(3+8)
b) 182
c) 03−a
d) 21.4

Answer 1

An algebraic expression is a mathematical expression that contains variables, numbers, and operations. Option C) 03−a is an example of an algebraic expression as it contains a variable and a subtraction operation.

Step-by-step explanation:

An algebraic expression is a mathematical expression that contains variables, numbers, and operations such as addition, subtraction, multiplication, and division.

A) O4(3+8) is not an algebraic expression because there are no variables present.

B) 182 is not an algebraic expression because it is a single number and does not contain any variables or operations.

C) 03−a is an algebraic expression because it contains a variable ('a') and a subtraction operation (-).

D) 21.4 is not an algebraic expression because it is a single number and does not contain any variables or operations.

Therefore, the correct answer is C) 03−a as it is the only option that meets the criteria of an algebraic expression.
