Ok this might be wrong but you don’t have much time so I will give my best

I’m pretty sure the of the x and y thing you do this you see the box with the number in it do this the top two says 2 and 4 the left side is x and the right side is y so you see at the bottom of the number Line thing on the right is a little x that where you start so the box of numbers the fist one says 2 so go to the bottom number line and there is the number two now the top right box with numbers says 4 so go up 4 squares from the number 2 and make a dot where they come together

Match each power of i with its multiplicative inverse.

erastovalidia [21]

By definition we have to:
In mathematics, the inverse multiplicative, reciprocal or inverse of a non-zero number x, is the number, denoted as 1/x or x -1, which multiplied by x gives 1.
We have then:

1) i
The multiplicative inverse is:
$\frac{1}{i}$
Rewriting we have:
$\frac{1}{i} \frac{i}{i}$
$\frac{i}{i^2}$
$\frac{i}{-1}$
$-i$
Answer 3) -i

2) i^2
The multiplicative inverse is:
$\frac{1}{i^2}$
Rewriting we have:
$\frac{1}{-1}$
$-1$
Answer 4) -1

3) i^3
The multiplicative inverse is:
$\frac{1}{i^3}$
Rewriting we have:
$\frac{1}{i*i^2}$
$\frac{1}{i^2}*\frac{1}{i}$
$\frac{1}{-1}*\frac{1}{i}*\frac{i}{i}$
$(-1)*\frac{i}{i^2}$
$(-1)* \frac{i}{-1}$
$i$
Answer 1) i

4) i^4
The multiplicative inverse is:
$\frac{1}{i^4}$
Rewriting we have:
$\frac{1}{i^2i^2}$
$\frac{1}{(-1)(-1)}$
$\frac{1}{1}$
$1$
Answer 2) 1
