uhmmmm i dont know how to solve it, if i give you the equation can you tell me how do it?

anonymous · Answer

Yes

anonymous · Answer

If you don't then we certainly cannot.

anonymous · Answer

$$3X ^{-2} Y ^{3} Z / 9X ^{3}-5 Z ^{2}$$ and the / = the bar line

anonymous · Answer

Okay, what do you need to solve for? More of, what are the specifics of the problem?

anonymous · Answer

you have to simplify it

anonymous · Answer

Just a simplification problem..

$$3x^{-2}y^3z \over 9x^3 - 5z^2$$

This is what you have?

anonymous · Answer

yesss thats what i have Polpak

anonymous · Answer

I'm not sure you can simplify that much except to get rid of the negative exponent on the top..
$$3x^{-2}y^3z \over 9x^3 - 5z^2$$$$={3y^3z \over x^2(9x^3-5z^2) }$$$$={3y^3z \over 9x^5-5(xz)^2) }$$

wouldn't you flip it ove the fraction bar?

anonymous · Answer

Well with exponents, you can bring them across the division by changing their sign.
