Why is 8 a perfect cube?

Perfect Squares and Perfect Cubes To get the square root, we simply divide the exponent by 2. For example x8 is a perfect square, its square root is x4 . x11 is not a perfect square. If a variable with an exponent has an exponent which is divisible by 3 then it is a perfect cube.

IS 400 a perfect square?

A number is a perfect square (or a square number) if its square root is an integer; that is to say, it is the product of an integer with itself. Here, the square root of 400 is 20. Therefore, the square root of 400 is an integer, and as a consequence 400 is a perfect square.

Is a perfect cube or not?

If the prime factors of a number are grouped in triples of equal factors, then that number is called a perfect cube. In order to check whether a number is a perfect cube or not, we find its prime factors and group together triplets of the prime factors. If no factor is left out then the number is a perfect cube.

Is 1000 a perfect cube?

The prime factor are not in the groups of triples. ∴100 is not a perfect cube. Now, 1000 is a perfect cube. Thus, the required smallest number is 10.
