Question

The set A= 1,4,9,16,25, ldots can be written in set-builder form as (A)  x: x is the square of an integer  (B)  x: x is the square of a natural number  (C)  x: x=n2., where .n ∈ R  (D) None of the above

Tardigrade Admin · Accepted Answer

We may write the set A as A= x: x is the square of a natural number AIternatively, we can write A= x: x=n2., where .n ∈ N .

Q. The set $A = {1, 4, 9, 16, 25, \dots}$ can be written in set-builder form as

${x : x$ is the square of an integer $}$

${x : x$ is the square of a natural number $}$

${x : x = n^{2}$ , where $n \in R}$

None of the above

We may write the set $A$ as
$A = {x : x$ is the square of a natural number $}$
AIternatively, we can write
$A = {x : x = n^{2}$ , where $n \in N}$ .

Q. The set A={1,4,9,16,25,…} can be written in set-builder form as

{x:x is the square of an integer }

{x:x is the square of a natural number }

{x:x=n2, where n∈R}
