My teacher just threw stuff on the board and said "always multiply by 4" and we all failed the test... you should replace him please

guys just wrote the i^n for a number x, when x=n(mod4)

[sebastian-nunez]

If you just figure out the remainder that’s gonna be the final power of i

[sagarpanta]

189 is not divided by 4 so, take the lower number which is divided by 4 like 188 then add how many numbers are needed to make it 189 ....it is 2 so, it will be 188.2

[andrewmwale]

10 x 0.5 is 5 sir, how did you get two I'm confused pliz🤔😑

[metites]

Why did you divide 42÷4 at 2:48??pls answer me

[JutnReacts]

[Oompaloompaseverywhere]

I know I'm 6 years too late, but the way he says "40" is so cute I can't-

[DcChatz]

You are still a great tutor though but you got your multiplying decimals wrong.
