Options

  1. AIf [x] be the greatest integer less than or equal to x, then ∑ _ n = 8 ^ 100 [ (- 1) ^ n n 2 ] is equal to:
  2. BIf [x] be the greatest integer less than or equal to x, then ∑ _ n = 8 ^ 100 [ (- 1) ^ n n 2 ] is equal to:
  3. CIf [x] be the greatest integer less than or equal to x, then ∑ _ n = 8 ^ 100 [ (- 1) ^ n n 2 ] is equal to:
  4. DIf [x] be the greatest integer less than or equal to x, then ∑ _ n = 8 ^ 100 [ (- 1) ^ n n 2 ] is equal to:

Correct answer

D. If [x] be the greatest integer less than or equal to x, then ∑ _ n = 8 ^ 100 [ (- 1) ^ n n 2 ] is equal to:

Step-by-step solution

In anti-ferromagnetic substances, the magnetic dipoles are oppositely oriented and cancel out each other's magnetic moment.
