If i = √-1 ,
then ...
i² = (√-1)² = -1
i³ = - √-1 = -i <== the answer to the question
i⁴ = (i²) · (i²) = (-1) · (-1) = 1
and then the whole thing starts over again, for higher powers of i .
The second one would be the correct answer
Answer:
x = 17/18
Step-by-step explanation:
-5(7-8x) -7x = -(3x+1)
-35 + 40x - 7x = -3x - 1
-35 + 33x = -3x - 1
33x + 3x = -1 + 35
36x = 34
x = 34/36
x = 17/18
You probably already know that the range of
is all non-negative real numbers, right?
No. of people don't like to be teacher
= 100% - 75% = 25%
