What expression is equivalent to 12x^6 y^-4 z^2/3x^2 y^-6 z^3? @sleepyjess @AnswerMyQuestions

OpenStudy (anonymous):

Is this it? \(\dfrac{12x^6y^{-4}z^2}{3x^2y^{-6}z^3}\) If it is, we just divide the whole numbers and subtract the exponents: \(\dfrac{12}{3}x^{6-2}y^{-4-6}z^{2-3}\)

OpenStudy (anonymous):

So first divide 12 / 3@boxercutie00

@boxercutie00 *

OpenStudy (anonymous):

Yes that is the equation.

OpenStudy (anonymous):

Okay, divide 12 / 3

OpenStudy (anonymous):

That would be 4

OpenStudy (anonymous):

Yes, now subtract 6 - 2.

OpenStudy (anonymous):

4

OpenStudy (anonymous):

Yep, -4 - 6

OpenStudy (anonymous):

-12

OpenStudy (anonymous):

Check again

OpenStudy (anonymous):

-10 haha my bad

OpenStudy (anonymous):

Yes, now lastly subtract 2 - 3.

OpenStudy (anonymous):

-1

OpenStudy (anonymous):

Wait, actually it should be -4 + 6..

OpenStudy (anonymous):

2

OpenStudy (anonymous):

Yes, so our final answer is: \(4x^4y^2z^{-1}\)
