Answer 2

Answer:

A = {1, 4, 9, 16, 25, 36, 49}

Step-by-step explanation:

We have,

A = {x : x = n² , n € N and n < 8}

Now,

we know that,

If n € N and n < 8,

then, it's possible values are

1, 2, 3, 4, 5, 6, 7

When,

x = n²

A = { 1², 2², 3², 4², 5², 6², 7²}

Thus,

A = {1, 4, 9, 16, 25, 36, 49}

Hope it helped and believing you understood it........All the best
