Answer 2

Question:

(-K) ×(-K)×(-K)×(-K)

Answer:

(-K) ×(-K)×(-K)×(-K)  = k^4

Step-by-step explanation:

(-K) × (-K)× (-K) × (-K)

= We know that if we multiply - and - means ( - * - = + ) gives out +

Therefore given that (-K) x (-K) = + k^2

As there are 4 K's we should take (-K) ×(-K)×(-K)×(-K)  = + K^4

= K^4 Hence Proved.
