1.	Can someone please evaluate,,-i^8 ( negative of iota power 8)And-i^5(negative of iota power5)
Answer» ANSWER: -1 & -i we know that i^2= -1 1) -i^8 = - (i^2)^4 = -(-1)^4 = -(1) = -1......... 2) -i^5 = - (i^2)^2 × i = -(-1)^2 × i = -(1)×i = -i.........

Can someone please evaluate,,-i^8 ( negative of iota power 8)And-i^5(negative of iota power5)

Answer»

ANSWER:

-1 & -i

we know that i^2= -1

1) -i^8 = - (i^2)^4 = -(-1)^4 = -(1) = -1.........

2) -i^5 = - (i^2)^2 × i = -(-1)^2 × i = -(1)×i = -i.........
