Re: Finding the second and third root of a square and cube.

Not exactly, it is a -36.


In mathematics, you don't understand things. You just get used to them.

I agree with you regarding the satisfaction and importance of actually computing some numbers. I can't tell you how often I see time and money wasted because someone didn't bother to run the numbers.

Re: Finding the second and third root of a square and cube.

According to the template we now just need to solve

we get

Now we have n1,n2 and n3 so

we have found the cube root of the RHS!

Hi;

Did you understand what happened? I can do more examples if you need them.
