(3xy2)3 x (-4x2y)
----------------------
(2x2y2)2

EDIT: EXPONENTS ARE COLORED ORANGE

Could someone show and explain step-by-step how to solve this?
My parents are making me do grade 9 math before I go to grade 9 so that I'm prepared and such, but I don't have anyone to teach me.


If no one is willing to help, could someone point me to a website that could?

I tried it out in store.

Great neck, nice n light, good tuning stability. Overall a good guitar. I didn't but it cause I generally only buy guitars over a grand now.

I did one step for you on the first one.

(27x^3y^6) x (-4x^2y)

Why don't you do your own homework TS?
Having somebody figure it out for you will not allow you the chance to use your mind to attack situations and practice your problem-solving techniques.

NOTE:

I'm very tired. Even though my entire career revolves around math, I may have made a simple mistake because I'm as tired as I am. Took me about 10 seconds.

I know it's a bit blurry but you should be able to make it out.

Edit: I kept this tab open a lot longer than I thought! Anyways I have explanations at the bottom.



Wow, thanks!

Makes sense now :>

oh, my parents tried to pull that on me "practise maths"
"...but i haven't learnt it yet"
"read the textbook"
"...no!"



xd

My textbook is complete balls when it comes to explanations, as it's supposed to be used alongside an actual teacher.


it helps a crapload, though. Last summer I did the grade 8 math textbook, and the entire year I got 95% (The highest they can give out here - 100% can't be given until highschool) in math. I outscored the asian kids :>
