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 x n2 = n3

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

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

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

Use Guassian quadrature with n=1 and n=2 and compare to exact value I=

If you mean n times 7 equals 56... Then the value of n is 8 !

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.

n=0.027

The value of n is 12.5

n = 8

The value of 'n' is 6

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

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 :)

2n plus 7 equals 19 2n equals 12 n equals 6

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

n + 5 = 18 n = 13

n= sqrt 225 = 15

n equals 52

The question gives the value of n. n MUST equal 0.222.

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.
