The numbers x^3 and y^3 are inversely proportional. If x = 2 when y = 15, what is y if x = 1 and y is positive? Write your answer in simplest radical form.
I will answer this again, taking into account that you said radical form.
As a note, you may have copied your question incorrectly as I know a question similar to this one but instead, one of them is x^2 and y^3 or x^3 and y^2. So, if you did miswrite it, please rewrite it and I will solve it correctly. :)
Inversely proportional means that the product stays constant. If x^3y^3 stays constant, then taking the cube root maens xy stays constant, so xy = 2*15 = 30, so when x = 1, y = 30. No radicals needed. :)
yes I am sorry I did make a mistake when copying the problem it should be "The numbers x^3 and y^2".
