Simplify i^89 in terms of complex numbers

Mathematics

I
because 89 is an odd number
and since i is root of -1
if the exponent is odd,
the result will always be i, the base.
On the other hand, if it is even,
the result will always be -1.

Hello from MrBillDoesMath!

Answer:

+2


Discussion:

-8 (17 - 12) / ( -2 (8 - (-2)) )  -

= -8 ( 5) / ( -2 ( 8+2))                          as 17 -12 = 5 and -(-2) = +2

= -40/ ( -2 (10))

= -40/(-20) =

= +2

which is the third choice.



Thank you,

Find the equation of a line given that: slope =5, y-intercept is (0,4). Standard form or slope intercept form?
Pie
So the slope is 5 and you know the points, (0,4)
y-4=5(x-0)
y-4 = 5x
y = 5x + 4 is the slope intercept form
standard form is: -5x + y = 4 OR y - 5x = 4
