n^3 mean a number Squared by 3

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

n squared minus n

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

If you mean n squared+11n+18 then it is (n+2)(n+9) when factored

If that's n squared, the multiples are n squared, 2 n squared, 3 n squared and so on. If that's n + 2, the multiples are n + 2, 2n + 4, 3n + 6 and so on.

answer is maths.

(n*n)+n

n2 + n2 = 2 n2

It is not an equation because it has no equality sign but it means xn squared-nx

No. Standard deviation is the square root of the mean of the squared deviations from the mean. Also, if the mean of the data is determined by the same process as the deviation from the mean, then you loose one degree of freedom, and the divisor in the calculation should be N-1, instead of just N.

n x n2 = n3

Given a set of n scores, the variance is sum of the squared deviation divided by n or n-1. We divide by n for the population and n-1 for the sample.

Take any positive integer n. If you square it, and subtract 1, you get (x squared - 1). If you take (n - 1) and (n + 1), and multiply them together, you get n squared - n + n - 1, which is the same as (n squared - 1).

Usually the sum of squared deviations from the mean is divided by n-1, where n is the number of observations in the sample.

n=number x 1 and n2 is n x n

are you sure you don't mean "4n squared - 26n + 42" ?? This would give 2(2n-7)(n-3) Davehx

The GCF is 2mn.

3 squared is 9 and so 9n = 63 which means n = 7

That depends on the value of "n". n2 (n squared) simply means "n" times "n".

n2 - 100 = (n + 10)(n - 10)

if you mean PI squared + PI squared / by 2 then that is.... 4.9298 solved on paper ... BUT if you mean what you said, the answer is YUMMY!

If you mean ex squared, the answer is e2x

If x squared equals n, then x is the square root of n.

One acre squared is equal to 4047 meters squared. So the formula to get n square meters is n x 4047=n x acres squared, that is because you will multiply 4047 times how many acres you want to find out.
