Answer 2

The builder form​ of set A is $A=\{\dfrac{1}{n^2}|n\in N, n\leq 5\}$.

Step-by-step explanation:

The given set is

$A=\{1,\dfrac{1}{4},\dfrac{1}{9},\dfrac{1}{16},\dfrac{1}{25}\}$

We need to write A in set builder form​.

Set A can be rewritten as

$A=\{\dfrac{1}{1^2},\dfrac{1}{2^2},\dfrac{1}{3^2},\dfrac{1}{4^2},\dfrac{1}{5^2}\}$

Set builder form​ of set A is

$A=\{\dfrac{1}{n^2}|n\in N, n\leq 5\}$

Therefore, the builder form​ of set A is $A=\{\dfrac{1}{n^2}|n\in N, n\leq 5\}$.
