Your casper the ghost Im jasper the child :p

Thank god I’m not the only one that thinks that

Hi there! If you're referring to how the variables on the bottom were removed that's because they went from the bottom of the fraction to the top of the fraction. You can see it on the right-hand side as negatives. (x^7 * y^9)/(x^4 * y^5) = (x^7-4 * y^9-5) Which simplifies to (x^3 * y^4). I hope this helps! Small clarification, variables in the denominator with exponents are equal to the variable to the variable on top with a negative exponent. For instance if you start with (1/x^2) this is equal to (x^-2) similarly 1/(x^4 * y^5) = (x^-4 * y^-5). To put all this together for the example shown the process (35 * x^7 * y^9)/(63 * x^4 * y^5) = (5 * 7 * x^7 * y^9)/(9 * 7 * x^4 * y^5) notice how there's a 7 on top and on the bottom? We can cancel those out. (5 * x^7 * y^9)/(9 * x^4 * y^5), recall that variables with exponents on the bottom become variables on top with a negative number. ((5 * x^7 * y^9) * (x^-4 * y^-5))/9 then multiplying across those variables results in (5 * x^7-4 * y^9-5)/9 which finally becomes (5 * x^3 * y^4)/9.

when youre diving, you subtract. I learned this song in math class. "Like base. Like bases. If you multiply you add, if you multiply you add, like bases. like bases. if you divide you subtract, if you divide you subtract, like bases. like bases. If its a power then you multiply, if its a power then you multiply, like bases. like bases. its kinda cringey but if you repeat it, it will actually help you. Anyways... so "if you divide you subtract" (in the song) you subtract the exponents, 2-4 = -2 . So what you get is 8-² (8 to the negative 2 power idk how you do the little subtract symbol) and if you dont want a negative exponent, you take 8-² ( 8 to the negative 2 power) you get the reciprocal of it. think of 8-² as 8-² over 1 or 8-²/1 and take the reciprocal which is 1/8-² and change the exponent to a positive so the answer is 1/8². I am very bad at wording so just let me know if you are still having trouble!

when you divide monomials you separate the power and the number. Basically just subtract the power Ex. 7⁴ / 3⁹ 9 - 4 = 5 7÷3 = 2.3

i might be wrong

Canadianbutt 275 uhh idk what youre trying to do...

Gaming - ActualBad 1/8^2

theres smoothdraw3 which is what khan academy uses but idk about him

Since the answer before that is 2 to the power of 3, you simply multiply 2 with 2, 3 times since the power defines how much you'll multiply by itself (sorry for bad english)

Jibriel Doria 7 is larger than three by four, making it a negative four

He took away 7 digits from 4 making it go into the negative (below 0). =4 - 7 =4 - 4 - 3 = 0 - 3 = -3

3 - 7 = WHAT??? 29???!?!? ITS NEGATIVE FOUR

Integers

= y3

y3

i failed 2 in a row lol

Same

@@wookiester6289 frick dude do something

I think its because if you were to multiply you do addition and so the same principal applies to division, you subtract They're similar operations

2^3 = 2 x 2 x 2 = 4 x 2 = 8

2x2= 4x2= 8, have you never learned exponents in 3rd grade?

Owen Zausch no or at least not that I remember

@@owenzausch7391 its not 3rd grade. for me atleast. i learned in like 6 or 7

@@benji4226 Am I the only who learnt them in 1st grade??

It's 8 because 2^3 is 8.

2x2x2 = 8 Numbnuts

when there is a small number above a number, that's an exponent. it inticates how much times the number multiplies my itself on a keyboard it is represented as 2^X for example 2^3 would be 2x2x2 and 2^5 would be 2x2x2x2x2

Ally WhatsGaming that's because he stopped teachimg!

dumb ass

Kobe Number2 no he didn’t, I sped it up in fact

im wathching it on 1.75x speed lool and its still slow

Ashley Campbell Lmao, I think you’re a potato

You literally have a ant size brain shut up

Then u should prob stop callin him a nerd u potato

Change the playback speed

the pause button exists for a reason-

There a playback speed for a reason

You realize if you don’t do this you won’t have a fake phone or computer to watch videos

Ashley Campbell are you 6 or something ffs

Ashley Campbell oh wait you won’t know what “ ffs “ means

what the actual fuck is wrong with you i hope your in highschool suffering on algebra because you didn't watch this

lol stupid, ignorant, no-brain

LOL!
