Answer:
Its hard to explain but essentially the zero in the 10 and 100 place cancels out the decimal essentially
Exercise 1:
The easiest way to compute powers of complex numbers is to write them in the form

In this form, you have

The magnitude of the number is given by

So, we have

As for the angle, we have

So, we have

Finally,

Exercise 2:
You simply have to compute the trigonometric function:

So, we have

You're basically doing 890 divided by 1, so the answer would be 800.. 800 ones.
Answer: opposite sides with equal length
Step-by-step explanation:
Answer:
5th option
52° bc its alternating interior with 2.
added together they would equal 180°
