Question

90x^9y^2*3z^3
--------------
15x^2y^7
show work please

Answer 1

(18 x^7 z^3)/y^5

Answer 2

i got this far
270x^9y^2z^3
--------------
15x^2y^7

Answer 3

how did you get that

Answer 4

simple cancellation

Answer 5

well.. it is a multiplication. You can cut the numbers

Answer 6

idk the english word for that but i believe it is what saifoo said.

Answer 7

hmmm.

Answer 8

i guess if i knew what you were talking about I wouldn't have asked for help

Answer 9

LOL.

u can say, its just multiplying and dividing by same number..


like in 6/4
the answer u get is 3/2

so u multiply & divide by 2

Answer 10

90x^9y^2*3z^3 90x^9*3z^3 y^2
-------------- = ------------- x ------
15x^2y^7 15x^2 y^7

isolating the second term:

y^2 1
------ = y^2 * y^(-7) = y^(2-7) = y^(-5) = ----
y^7 y^5

Now you just need to do this for "x" and "z". Understand now?

Answer 11

LOL isolate the equation like this:

90x^9*3z^3 y^2
----------- x ----------
15x^2 y^7


if you take only on the second term:

y^2 1
-------- = y^2 * y^(-7) = y^(2-7) = y^(-5) = -----
y^7 y^5


now you just need to do the same for the "x"
