Step-by-step explanation:

Graph it using a graphing calculator. The solutions are the points where the graph crosses the x-axis.

I attached a photo of the graph, you can see that the graph crosses the x-axis at points -2 and 4

These are the solutions!

tensa zangetsu [6.8K]

Answer:

x^8 * y^3

Step-by-step explanation:

Square both sides to get (x^10 * y^4)/(x^2 * y). Divide both sides by x^2 to get (x^8 * y^4)/y. Divide both sides by y to get x^8 * y^3.
