One algorithm that is simple, but not very efficient, is to try out different numbers. Example, cubic root of 10:

2 cubed is 8, which is less than 10

3 cubed is 27, which is greater than 10

So the cubic root of 10 would be somewhere between 2 and 3; you can continue narrowing it down that way.

A calculator or computer program such as Excel would probably solve a cubic root - or any other root for that matter - using powers. For example, the cubic root of 10 is the same as 10 to the power (1/3).

Powers, in turn, are calculated using infinite series, using the formula:

a ^ b = exp(b ln a)

In this formula, exp() is the exponential function (e to the power ...), and "^" stands for power.

An "infinite series" is not as bad as it sounds; you don't actually calculate an infinite number of terms. Rather, the terms in an infinite series get smaller and smaller, once the terms are smaller than the desired accuracy, you can stop. It's actually a bit more complicated than that, but that's the basic idea.

All numbers have cube roots (not necessarily integral cube roots) so every prime has cube roots.

Yes.

Many calculators will offer a way for you to do cube roots, or what number to the power of 3 will equal that number. There is no easy way to go about finding cube roots without a calculator, so I suggest not trying too hard.. but the cube root of 7 is 1.912931182772389 found from using a simple Cube Root calculator you can find on the internet.

The answer depends on "different from WHAT?" Positive cube roots, or negative square roots?

I think you mean rubix cube. For a rubix cube, you just use a variation of algorithms.

You learn algorithms and practice. When you have practiced for a while then you solve the cube faster maybe in 30 secounds or so.

No, it doesn't but it can increase your understanding about various aspects of geometry. The people who are able to solve a rubik's cube don't really have higher IQ. They are able to do this because they have learn't the trick to solve it. They have hardcoded the algorithms in their brains. Anyone can solve a rubik's cube just by memorizing the algorithms and learning the technique to solve it.

Advice: If you want to get good at beating the cube, I would learn the algorithms by heart. Seriously, there is no way around this. But if it's just a one time thing, you can just follow the algorithms and forget about it. Dan Brown's tutorial on YouTube is really helpful, there are only a few algorithms.

Actually there is no secret! If you want to solve a rubix cube then you can do it, just learn the rubix cube solution method (I added a link). With this rubix cube solution you'll be able to solve the rubix cube shortly.

First thing is to remember the algorithms of the cube. Then, you have to solve a cross, and put the corners in the correct position. After that, you solve for the second layer, and then you do the final layer. I would recommend searching it up on YouTube to assist you.

there are many, and the algorithms used vary depending on the setup of the cube, but really there are several steps that are followed to solve it, however, writing out all the algorithms is nnot worth it and i recommend watching an instructional video on youtube

The 360 really can't be classified as a Rubik's cube. There are no algorithms in the 360, because of that the 360 can only be solved with dexterity. Like the labyrinth maze.

The Rubik's cube is normally easier because you can us algorithms as techniques to solve it where as the rubik's 360 is based on luck and steadiness of the hand.

Algorithms, my friend, algorithms.

There's not a specific amount, but if you haven't learned yet, you may not know that there are methods to solving the Rubik's Cube (obviously, since people can solve them in 7 seconds). All Rubik's Cube methods involve algorithms. All an algorithm is is a series of moves that you do to accomplish something on the cube. For example, "R U R' U R 2U" is an algorithm. Although there isn't a set number of moves to solve a Rubik's Cube because of how many possibilities you can get from scrambling, there are, however, only 7-9 algorithms that one must memorize to solve the Rubik's Cube. That's only the beginner method, whereas in more advanced methods you could learn 70+ algorithms to solve the cube. The advanced methods help one to accomplish layers of the cube faster so as to decrease solve time.

No, you need to memorize certain algorithms for different situations you have with your Rubik's Cube. It comes easier for some than others and it take time.
