Yes, Hanna, I would be happy to explain.
To solve an equation with two unknowns (x and y in this case), you need at least two equations, and we only have one equation, so we can’t find a unique solution. In this case, all the libraries in the world wouldn’t be big enough to show all the solutions, because there is no limit to the number of solutions.
However, we can draw a wiggly graph, which is a line, every point on which corresponds to an x and y value that fits the equation. Since the line is continuous and infinitely long and includes negative as well as positive values for x and y, we will go on forever writing all possible points. Not only that, all the solutions are irrational, which means we won’t be able to find any x and y values which are both exact fractions or exact decimals.
∛4 means the number which multiplied by itself twice = 4. The number 1.587 comes close: 1.587×1.587×1.587=3.996969... but it’s not exact, and there is no exact decimal that would give us 4 this way. I hope you understand my explanation. Thank you for asking.
