\[\frac{(10x^4y^2)^3}{(-5x^3y^2)}\]

Is that the problem?

yes

Ok. Now xXDWEAHXx87 wants to explain it to you. Good bye and good luck.
OpenStudy (anonymous):
o i will
OpenStudy (anonymous):
ok so 10 times 10 =100, times 10 =1000, now, x to the fourth times x to the fourth is x to the 8th, times x to the 4th is x to the 12th, then y squared times y squared is y to the 6th so u have \[1000x^12y^6 divided by -5x^3y^2\]
OpenStudy (anonymous):
whoops, its supposed to be x to the 12th
OpenStudy (anonymous):
then 1000 divided by -5= -200 and x to the 12 divided by x to the 3 equals x to the 9 and y to the 6 divided by y to the 2 equals y to the 4 so it is \[-200x^9y^4\]

hey can u tell me how i would add up \[(3x^3y)(3x^3y)(-4x^2y^4) (-4x^2y^4) (-4x^2y^4) \]
