## Why is 9 a square?

A square can be defined as a four sided regular polygon with all sides equal in length and all four angles right angles (90 degrees). The number 9 is in fact a perfect square because it can be expressed as the product of an integer multiplied by itself.

In this case, 3 × 3 = 9. Furthermore, the square of 9 can be thought of as the area of a square with sides length of 3. Therefore, 9 is a square.

## Is a 9 perfect square?

No, 9 is not a perfect square. A perfect square is a number that is the result of squaring another number, meaning that it is the product of some number multiplied by itself. For example, 4 is a perfect square because 2 x 2 = 4.

9 is not the result of any number multiplied by itself, so it cannot be a perfect square.

## Can a square number be negative?

No, a square number cannot be negative. A square number is defined as the product of an integer multiplied by itself. When both integers are negative, the product will always be positive, meaning a square number can never have a negative value.

## What number is not square?

Any number that is not a perfect square is not square. A perfect square is an integer that can be written as the product of two identical integers, or a number multiplied by itself. Examples of perfect squares are 4 (2×2), 9 (3×3), 16 (4×4), etc.

Most numbers are not perfect squares and are therefore not square.

## What type of number is 1000?

1000 is an integer, which is a type of number that does not have any fractional or decimal parts. Integers can be either negative (e.g., -5), zero (0), or positive (e.g., 5). In the case of 1000, it is a positive integer.

## Is 1000 a perfect cube or not?

No, 1000 is not a perfect cube. A perfect cube is a number that can be expressed as the cube of an integer. An example of a perfect cube would be 8 (2³). A number such as 1000 can not be expressed as the cube of an integer.
