Question

anonymous · Answer

just starting the problem, not sure of the answer yet. 

the way to set up this problem is like this:

x^3=x-1

anonymous · Answer

and actually that's impossible. just decided.

josee · Answer

it is possible. lol

josee · Answer

the book is saying there is a number. but that's all it says

anonymous · Answer

the reason being:

1^3 = 1

so anything less than 1 is going to have a cube smaller than itself. but if you subtract one from any of those numbers you will get a negative number which is less than 1 away from its cube

anonymous · Answer

could you restate the question? you are looking for a number that is exactly one more than it's cube?

josee · Answer
