We could multiply both sides of this equation by x squared. And we would get 40x to the third is equal to 180. Divide both sides by 40. You get x to the third is equal to 180 over 40, which is the same thing as 18 over 4, which is the same thing as 9 over 2. And so if we want to solve for x, we get that x is equal to a critical point. We get a critical point at x is equal to 9 halves to the 1 third power, the cube root of 9 halves. So let's see.
