Thread: Exponent Rules

I know that it would be x^5 over y^4, 2^4 over x^4, and y^3 over 4^3
Now can I just group like terms. x^9 y^8, and change 4^3 to 2^2^3 for same bases. Thanks for your help!!!!!!!

PS- I'm sorry about the gigantic question size. It's what photobucket.com gave me.

You get,
(x^5/y^5)(16/x^4)(y^3/64)
Cancel the x's,
(x/y^5)(16)(y^3/64)
Cancel the y's
(x/y^2)(16)(1/64)
Cancel the numbers,
(x/y^2)(1/4)
