If i is raised to an odd power, then it can not simplify to be
Tomtit [17]
A real number

ok so
any even power is i^(2n) where n is a whole number
if n=1
i^2=(√-1)^2=-1

if i^3, then it is equal to (i^2)(i)=(-1)(i)=-i
if i^4, then it is equal to (i^2)(i^2)=(-1)(-1)=1

therefor
i^1=i
i^2=-1
i^3=-i
i^4=1
then it repeats

look at the odd powers
i and -i
they are complex

therefor

if i is raised to an odd power, it cannot be simplified to be a real number

Geometry math question no Guessing
bearhunter [10]
We can first look into the properties of parallelogram,you can also take reference from the figure above:

-Opposite sides are parallel and are congruent.
-Opposite angles are congruent.
-The diagonals bisect each other.

We can then look into the answer:

A.Opposite angles are congurent.
-This is an correct statement.

B.Diagonals are congruent.
-This is incorrect,although they bisect each other,they do not have the same length.

C.The diagonals are peroendicular to each other.
-This is incorrect as well,not every parallelogram has the angle of 90° in the place where the diagonals bisect each others.

D.The area is equal to the product of two adjacent side-this is not true,to find the area,it have to be base×height.

Therefore the answer is A.

Hope it helps!
