c=0 -> √8 = √-8 = -√8

Or if you mean √(8-c) = c-8: (8-c)=(c-8)2 (8-c)=(c2-16c+64) c2-16c+64-(8-c)=0 c2-15c+56=0 using quadratic equation => c=8 (√0=√0)

What is the number of groups of order 8 upto isomorphisms?

There are 5 groups of order 8 up to isomorphism. 3 abelian ones (C8, C4xC2, C2xC2xC2) and 2 non-abelian ones (dihedral group D8 and quaternion group Q)


How do you add numbers on a spreadsheet?

In EXCEL spread sheet you can click and hold on first number, scroll down or across the numbers you want to add to next available blank cell, and then release key and hit the summation toolbar. Or, you can add numbers by command =SUM(C1:C8) for example, where C is column to sum from rows 1 to 8


What is the numbers of groups of order 8 upto isomorphisms?

There are five groups of order 8: three of them are Abelian and the other two are not. These are 1. C8, the group generated by a where a8 = 1 2. C4xC2, the group generated by a and b where a4 = b2 = 1 3. C2xC2xC2, the group generated by a, b and c where a2 = b2 = c2= 1 4. the dihedral group 5. the quaternion group


How do you calculate time complexity for insertion sort?

1.for j = 2 to length[A] c1 n 2. do key ¬ A[j] c2 n-1 3. //insert A[j] to sorted sequence A[1..j-1] 0 n-1 4. i ¬ j-1 c4 n-1 5. while i >0 and A[i]>key c5 Sum (j=2->n) tj 6. do A[i+1] ¬ A[i] c6 Sum (j=2->n) (tj -1) 7. i ¬ i-1 c7 Sum (j=2->n) (tj -1) 8. A[i+1] ¬ key c8 n -1 Sum j=2->n tj evaluates to (n(n+1)/2)-1 and j=2->(tj-1) evaluates to n(n-1)/2 thus the highest order term after droping constants becomes n2 thus the complexity is n2
