IS 729 perfect square or perfect cube?
It is both because 27*27 = 729 and 9*9*9 = 729
What is a perfect cube number?
A perfect cube is the cube of an integer (whole number). This means that, for n to be a perfect cube, n = x3, x∈ℤ Eg. ±1 [=(±1)3], 8 [=(±2)3], ±27 [= (±3)3], etc.
Is 77 a cube number?
If by cube you mean perfect cube (a cube of an integer), then no, and the nearest perfect cube is 81.
Is 27 a perfect square?
No, it's a perfect cube.

IS 729 perfect square or perfect cube?
It is both because 27*27 = 729 and 9*9*9 = 729
What is the largest perfect cube factor of 189?
To find the largest perfect cube factor of 189, we first need to factor it into its prime components. The prime factorization of 189 is (3^3 \times 7^1). The largest perfect cube that can be formed from these factors is (3^3), which equals 27. Therefore, the largest perfect cube factor of 189 is 27.
What is perfect square and perfect cube?
The square root of a perfect square and the cube root of a perfect cube is always an integer. A perfect square is a number multiplied by itself. A perfect cube is a number multiplied by itself twice. Example: 3 x 3 is 9, the square of 3 3 x 3 x 3 is 27, the cube of 3
What is a perfect cube number?
A perfect cube is the cube of an integer (whole number). This means that, for n to be a perfect cube, n = x3, x∈ℤ Eg. ±1 [=(±1)3], 8 [=(±2)3], ±27 [= (±3)3], etc.
What are the perfect cubes between 10 and 30?
The perfect cubes between 10 and 30 are 27, which is the cube of 3 (3^3). The next perfect cube, 64 (4^3), exceeds 30, while the perfect cubes below 10 are 1 (1^3) and 8 (2^3). Therefore, 27 is the only perfect cube in that range.
Is 30 a perfect cube?
No, 30 is not a perfect cube. A perfect cube is a number that can be expressed as the cube of an integer, such as (1^3 = 1), (2^3 = 8), or (3^3 = 27). The cube root of 30 is approximately 3.11, which is not an integer, confirming that 30 cannot be written as the cube of any whole number.
Is the number 28 a cube number?
No 3 cubed is 27 4 cubed is 64 Strictly it is the cube of the cube root of 28. The common description is that it is not a perfect cube.
