@@Shosholovee cause you want to make that exponent to be in form i^4*y + i^z, cause we know i^4 is equal to 1. Example i^2021 is same as if you write i^4*505+i^1 which leads to answer i^2021=i.

For question 5, why did he have to divide 59 by 4?

@gospheltube1011 3 года назад

I think he used it to simplify i^59 59 is odd number,,,,but he got 14.75 if u multiply 4 with 14.75 u wont get 59 but by 14 u will get ,i think he used for this reason

@theosuleymanov2057 2 года назад

Because i^1=i İ^2=-1 i^3=-i i^4=1 and then i^5=i^4•i if i^4=1 then i^5=1•i=i .and it will going on like this (Sorry l don't know that much English)

@TaylorPlays_ 2 года назад

@@rosacamelasaguid262 what is?

@oriehossain2410 2 года назад

@@jalynnhawkins7 because if you take i^4, it equals to one. So what he did was make life easier for himself and express the 59 in terms of groups of 4. 1 to the power of any number is always 1. When he divided 59 by 4, you get 14 with a remainder of 3. Meaning that he can (according to index law) express i^59 as (i^4)^14 * i^3. Since i^4 equals to 1 (this is because i^2 is -1 and i^4 can be expressed as i^2 * i^2, which then equals to 1), the equation is 1^14 * i^3. Since 1 to the power of anything is 1, 1^14 is just 1. Therefore the equation simplifies into 1 * i^3. Now, i^3 is just i^2 * i, which is just -i (as this was obtained from -1 * i). The equation then further simplifies into 1 * -i which is just -i, which is how he got his answer :)

i don"t understand in question number 5. Why did you decided to divide 59 with 4?

@lesserknownfacts7849 4 года назад

Its because of a pattern. First I am gonna tell you the pattern. i = -1^1/2 i^2=-1 i^3=i^2*i=-1*i=-i i^4=i^2*i^2=-1*-1=1 Now this pattern repeats at intervals of 4th power. example i^8=1 i^12=1 i^16=1 so, i^n= i^r (r is the remainder you get after dividing n by 4) I hope this helped you.

@melodycruz3032 2 года назад

I'm so sorry but I just want to ask why "i square" is equal to -1 ? Sorry to ask ., But I hope you'll answer thanks

@eeriemyxi 2 года назад

well, i variable is used to denote √-1 sometimes. square root of a number x, gives us the value which when multiplied by itself (x × x or x^2) gives back x. (√x)^2 = √x × √x = x so, (√-1)^2 = √-1 × √-1 = -1 2 months late but oh well!

@zapper354 2 года назад

On #9 I think I caught a mistake. When you add 16+9 on the denominator I think it should be 16-9 because the addition sign is being carried over by the 12i which got canceled out already. Anyway the different answer I got after catching the mistake was 18/7 +17i/7

@denzelsythan4074 2 года назад

You are wrong boss check the solutions again

@nevaskomaeda3051 2 года назад

Old but that doesn't happen. X - X becomes 0, so it's like having 16+0-9i^2. You could use an addition or subtraction sign for the 0 and it wouldn't change a thing. It becomes 16-9i^2 and i^2 becomes -1 and it obviously then turns into 16+9.
