What is the value of i^20+1?
ICE Princess25 [194]

You know

i^2=-1

Squaring both sides gives

(i^2)^2=(-1)^2\implies i^4=1

Then raising both sides to any integer power n gives

(i^4)^n=1^n\implies i^{4n}=1

That is, any power of i where the power is a multiple of 4 will always be equal to 1.

So

i^{20}+1=1+1=2

But perhaps you mean to write 20+1 as the exponent, in which case

i^{20+1}=i^{20}i=i

Your friends shuffle the cards and then deal them. Select probability of getting a red card. Select probability of getting a spa
sladkih [1.3K]

Answer:

1/2 ; 1/4

Step-by-step explanation:

Number of cards in a deck = 52

Number of red cards = 26

Number of spades = 13

Probability of event A :

P(A) = required outcome / Total possible outcomes

P( red card) = number of red cards / total cards in deck

P(red card) = 26 / 52 = 1/2

P(spade) = number of spades / total cards in deck

P(red card) = 13 / 52 = 1 / 4

Find the difference.<br><br> 6rs – (-2rs)
lilavasa [31]
There is no difference, 6rs-(-2rs) if you get rid of the parenthesis you are left with 6rs- -2rs and two negatives make a positive therefore the answer will become 8rs... I hope this helps :)
