Answer:
0
Step-by-step explanation:
i^1 = i
i^2 = - 1
i^3 = i^2 * i = - 1
i^4 = i^2 * i^2 = -1 * -1 = 1
Now the circle just repeats itself. So what you do is find out the remainder of i^97 which you divide by 4. What you get is 24 with a remainder of 1.
So i^97 = i
i - i = 0
The answer is 0
Answer:1/5
20/100=1/5
x=21
x-4 + 3x +100=180
x + 3x =84(180-100-4)
4x=84
x-4=17
3x21=63
100+21+63=180
$(0.50+0.75n)
$6.50
