Question

What did you do to determine whether the numbers are perfect squares?

Answer 1

Answer:

A perfect square is a number which is generated by multiplying two equal integers by each other.

Step-by-step explanation:

For example, number 9 is a perfect square because it can be expressed as a product two equal integers being: 9 = 3 x 3.

Answer 2

A number is a perfect square when its square root obtained is a whole number.

• When you multiply an integer by itself, you get a perfect square, which is a positive integer. Perfect squares are sums that are the products of integers multiplied by themselves, to put it simply.
• A perfect square is typically expressed as x², where x is an integer and x²'s value is a perfect square. By squaring a whole number or an integer, one can create perfect squares.

Now, according to the given information,

Let us suppose that a number x is given and we need to check if this number x is a perfect square.

When we exact the rules of square root on this number and find the square root by any method from the methods of long division to prime factorization, if the result obtained is a whole number, the original number is a perfect square.

If not, then the number is not a perfect square.

Hence, a number is a perfect square when its square root obtained is a whole number.
