Best ResponseYou've already chosen the best response.0Can you use the equation editor or the draw tool to show what you mean? Is it this? \(\Large \dfrac{4xy^3 + 8x^2y^5}{2xy^2} = 2x^ay^b + x^cy^d\)

Best ResponseYou've already chosen the best response.1Value of a is zero 2xy2(2y+4xy3)2xy2 cancels the 2xy^2 on top and bottom =2y+4xy3=2x0y1+4x1y3 so x^a= x^0 a=0

Best ResponseYou've already chosen the best response.0I understand what the question is asking. My question is if the above expression is correct.

Best ResponseYou've already chosen the best response.0You can separate the left side into two fractions. \(\Large \dfrac{4xy^3 + 8x^2y^5}{2xy^2} = 2x^ay^b + x^cy^d\) \(\Large \dfrac{4xy^3}{2xy^2} + \dfrac{8x^2y^5}{2xy^2} = 2x^ay^b + x^cy^d\) Now reduce each fraction. When you divide powers with the same base, subtract the exponents.

Best ResponseYou've already chosen the best response.0Now you can compare each exponent on the left side with each variable, a, b, c, and d, on the right side to see what value each of those variables has.
