Simply each of the following powers i. i^15=

-i

Step-by-step explanation:

i = √-1, i² = -1, i^4 = 1

i^15 = i^4 • i^4 • i^4 • i² • i

= 1 • 1 • 1 • -1 • i

= -i

-i

Step-by-step explanation:

i means Imaginary unit.

i to the zero power is 1

i to the first power is itself

i to the second power is -1

i to the third power is -i

Then, i to the fourth power is 1, so it all repeats again.

step-by-step explanation:

worked it out i believe

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
