Can't quite tell what you mean by n3.
1) If that's n3, then:
If n3 is even, it can be expressed as n * n * n = 2 * t (t is a natural number).
You can see that two is a factor of n3, and so it has to be a factor of n, because there is no ther number that could contribute to it. So n is even too.
2) If you mean 3 * n, then:
3 * n = 2 * t, where t is a natural number.
Again, the only number to contribute factor 2 for the right side of equation is n.
So n has to be even too.

What does n3 mean in maths?
The statement n3 is ambiguous. I presume you mean n3, which means n cubed or n to the power of 3 (n*n*n). However, n3 (which should really be written as 3n) means n times 3 (n*3).
How do you find the smallest positive integer of a variable in a cube root so that the cube root is an integer ex. find the smallest positive integer g so that the cube root of 400g is an integer?
Here is a method: cube root of 400g = n, where n is an integer cube both sides: 400g = n3 then: g = n3/400 therefore: n3/400 must be an integer if this is so, then n3 must be divisible by 400 with no remainder, and n must be => cube root of 400 which is 7.368 bracket the answer by substitution: let n=8, n cubed = 512 no good let n=12, n cubed = 1728 no good let n=20, n cubed = 8000, 8000/400=20 OK No smaller value of n will be divisible by 400 without a remainder, so g=20 is the smallest positive integer that meets the requirement.
What is six more than the cube of a number?
If ' N ' is the number, then six more than the cube of the number is (N3 + 6).
How do you determine this sequence -3 4 25 66 133 232 369 550?
Un = n3 + n2 - 3n - 2 for n = 1, 2, 3, ...
For all integers m and n if mn is an even then m is even or n is even?
If m * n is even, it can be expressed as m * n = 2 * t, where t is natural number. Either m or n has to provide factor of 2 for the right side of equation, so it basically means at least one of them has to be even.
Why a number when it is to the power of zero is equal to one?
Let any number be n:- n3/n3 = n*n*n/n*n*n = 1 And in index form: n3/n3 = n3-3 = n0 = 1
What is n3 plus 1?
n3 + 1 = n3 + 13 = (n + 1)(n2 - n + 12) = (n + 1)(n2 - n + 1)
What does n3 mean in maths?
The statement n3 is ambiguous. I presume you mean n3, which means n cubed or n to the power of 3 (n*n*n). However, n3 (which should really be written as 3n) means n times 3 (n*3).
What would n equals in the equation n3 equals 8?
If: n3 = 8 Then: n = 2
What is n cubed?
N cubed
What is the simplest formula for nitride?
The chemical formula for a nitride ion is N-3.
What is n n squared equals?
n x n2 = n3
Do 6 plus N3 and 6N3 have the same answer?
6+N3 is the sum of N*3 then you add six. 6*N3 is you multiply 6 times three times N times three.
What is the proof for if n cubed is odd then n squared plus one is even?
No even values of n will give give an odd value of n3, so n must be odd.When n is odd, n2 is also odd, so n2+1 must be even. ■
What is n - 1 - n - 1 - n - 1 simplified?
N3-13
Factor the polynomial by grouping n3 plus 3n2 plus 4n plus 12?
n3 + 3n2 + 4n + 12 = (n3 + 3n2) + (4n + 12) = n2(n + 3) + 4(n + 3) = (n2 + 4)(n + 3).
Why is the third power of a number cubed?
Let the number be n.Then (n3)3 = n3 x 3 = n9.........or n to the power nine.However, if the question is what the the one-third power of a number cubed, then:(n3)1/3 = n3 x 1/3 = n1 = n
