Conditional statement: If n2 equals 64, then n equals 8, where n2 equals 64 is the hypothesis, and n equals 8 is the conclusion. In order to obtain the converse of the conditional we reverse the 2 clauses, then the original conclusion becomes the new hypothesis and the original hypothesis becomes the new conclusion. So that, Converse: If n equals 8, then n2 equals 64.

so 3n2 = 15 ie n2 = 5 so n = sqrt 5
If: n squared -n -90 = 0 Then the solutions are: n = 10 or n = -9
n x n = n2
You are looking for the square root of 225 which is 15. (15x15=225)

n x n2 = n3
n2 + 9n + 18 = (n + 6)(n + 3)
If: n2 = 19 Then: n = the square root of 19.
If you mean: 6/n times 5/n-1 = 1/3 Then: 30/n2-n = 1/3 Multiplying both sides by n2-n: 30 = n2-n/3 Multiplying both sides by 3: 90 = n2-n Subtracting 90 from both sides: 0 = n2-n-90 or n2-n-90 = 0 Solving the above quadratic equation: n = -9 or n =10 If n is of a material value its more likely to be 10 Note that n2 means n squared
(n + 4)(n - 4)
n=40 n2+n+41=1681 which is not a prime.

n = +5 or -5
n2 = 20 + n so n2 - n - 20 = 0 that is (n - 5)(n + 4) = 0 so that n - 5 = 0 or n + 4 = 0 n = 5 or n = -4
Sn = n2 S12 = 122 = 144.
