Let n be any integer (..., -4, -3, -2, -1, 0, 1, 2, 3, 4, ..., etc.)
If 9 was a cubed number, it means n x n x n = n3 = 9
If 9 was a square number, it means n x n = n2 = 9
You should memorize the first few (some might even suggest the first 15 or 20) square numbers. Being able to recognize them comes in handy in higher level mathematics. With that said, we know:
3 x 3 = 9, therefore 9 is a square number
Since 3 x 3 is equal to 9, that means if a number curbed had a product of 9, than that number would have to be less than 3 (if we took 3 cubed, we'd get something higher than 9).
2 x 2 x 2 = 23 = 8
8 is less than 9 and because any factor lower than 2 will be less than 8, which is less than 9, 9 cannot be not cubed.
The answer is 9 is a squared number.
Bonus Information: A number can be both curbed and squared. In fact any number raised to the sixth power is both square and cubed.
e.g., 26 = 64
√64 = 641/2 = 8
641/3 = 4
Therefore 64 is both square and curbed.
The smallest (arithmetically lowest) one-digit number is -9. Cubed , or (-9)3 is -27. (-9) x (-9) x (-9) = -27
9 x 9 x 9 = 729 9 cubed gives the answer 729 so the answer is 9 (please note 8 cubed is 512 and 10 cubed is 1000)
Here, combine the exponents of the units and multiply the values as usual to get: 120 * 30 * meters5 = 3600 meters5
-3 cubed is simply (-3)(-3)(-3), so -3 x -3 = 9 and 9 x -3 = -27 ... As a guideline, when a number is cubed the answer will have the same sign (positive or negative) as the number you start with.

The smallest (arithmetically lowest) one-digit number is -9. Cubed , or (-9)3 is -27. (-9) x (-9) x (-9) = -27
3 cubed = 27 and 9 squared = 81 which is the biggest number
9 x 9 x 9 = 729 9 cubed gives the answer 729 so the answer is 9 (please note 8 cubed is 512 and 10 cubed is 1000)
It is n3 - 9.

'9 Cubed' means 9 X 9 X 9 9 x 9 = 81 )9 squared) Then 81 x 9 = 729 (9 cubed)
64 and 81 are squares of whole numbers. 64 is the square of 8 (8x8=64) and 81 is the square of 9 (9x9=81).
9 cubed is equal to 729.
3 cubed (3^3 or 3³) = 27! 3 x 3 = 9 9 x 3 = 27! Hope this helps!
