How do you code a square in Java?

In general I just multiply the number by itself to get the squared value, but the advantage of the Math. pow method is that once you know how to use it, you can easily cube a number like this: int i = 2; int square = Math. pow(i, 3);

How do you check a number is perfect cube or not in Java?

The idea is to use the inbuilt function (cbrt()) to find the cube root of a number which returns floor value of the cube root of the number N. If the cube of this number equals N, then N is a perfect cube otherwise N is not a perfect cube.

Is 10000 a cube number?

What is the Cube Root of 10000? The cube root of 10000 is the number which when multiplied by itself three times gives the product as 10000. Since 10000 can be expressed as 2 × 2 × 2 × 2 × 5 × 5 × 5 × 5. Therefore, the cube root of 10000 = ∛(2 × 2 × 2 × 2 × 5 × 5 × 5 × 5) = 21.5443.

How do you find the perfect cube between two numbers?

Javascript. Method 2 (Efficient): We can simply take cube root of ‘a’ and cube root of ‘b’ and Round cube root of ‘a’ up and cube root of ‘b’ down and count the perfect cubes between them using: (floor(cbrt(b)) – ceil(cbrt(a)) + 1) We take floor of cbrt(b) because we need to consider numbers before b.
