3 squared is 9 and so 9n = 63 which means n = 7
It equals a nonsense. Some of the measures are areas in 2-dimensional space while others are measure of volume in 3-dimensional space. According to basic principles of dimensional analysis, combining them together is not valid.
using n to represent the number. n^2 when squared rooted equals the original number, n; and when a number squared rooted is squared, it also equals to the original number. Hence the relationship is, when either of the operations is applied to the opposite operation (i.e. n^2 is opposite to square root of n) is result is always the original number, n. Hope I didn't confuse you too much :)
3(3n - 1)(n + 1)

Simple equation lad. In your example, you said n=4 and x= n squared + n - 1 + (n-2)squared + (n-3)squared. You simply write n²+n-1+(n-2)²+(n-3)² I hope that is what you mean by what you say. P.S. To get the to the power of sign, hold alt and press 0178 for ², and 0179 for ³
If x squared equals n, then x is the square root of n.

The square root of 7921 is 89.

If: n squared -n -90 = 0 Then the solutions are: n = 10 or n = -9

n squared x n n x n x n = n cubed n x n = n squared n squared x n = n cubed

This is a hyperbola. It is best approached using Fermat's factorisation method. Seefermat-s-factorization-methodor google wikepedia. I don't know of any faster approach.

Oh, dude, adding n squared plus n squared is like adding apples to apples, you know? It's just like, you take two n squared terms and you add them together to get 2n squared. It's not rocket science, man. Just double up those n squares and you're good to go.
