Use the definition of "cubed". 7 billion cubed is the same as 7 billion x 7 billion x 7 billion.
8 is 2 cubed 27 is 3 cubed
The first 5 cubed numbers are 1x1x1=1, 2x2x2=8, 3x3x3=27, 4x4x4=64 and 5x5x5=125. :)
The integers with cubed values between 2000 and 3000 are: 133 = 2197 143 = 2744
216 & 343
A number can't be cubed and prime. Cubed numbers (other than 1) have more than two factors.
The sum of the first n cubed numbers is the square of the nth triangular number.
Yes. For example 3 is the cube of cuberoot(3). However, by definition, a prime number cannot be a PERFECT cube.
The sum of the first n cubed numbers is: [n*(n+1)/2]2 which is the same as the square of the sum of the first n numbers.
Numbers multiplied by it's self 3 times
2,628,071 and 2,628,073. 138 cubed is 2,628,072
Use the definition of "cubed". 7 billion cubed is the same as 7 billion x 7 billion x 7 billion.
Perfect cubes.
1, 8, 27, 64
8 is 2 cubed 27 is 3 cubed
If you mean the sum of two cubed numbers then the answer is simply 'none' with the trivial exception of all of them being 0. For more info check out "Fermat's last theorem".
