Find the "y [root symbol] x" button on your advanced calculator. This button makes finding the cube root of any number quick and easily. Press the "y [root symbol] x," followed by the number you want to find the cube root of.
For example:. Paul Lin has been writing professionally since He has written scripts for the National Science Foundation and short films that have won awards at film festivals.
Here is the list of some of the non-perfect cubes rounded to the hundredths:. Don't hesitate to use our cube root calculator if the number you want and need is not on this list!
Unlike e. This function also passes through zero. Thanks to this function you can draw a cube root graph, which is shown below. We also encourage you to check out the quadratic formula calculator to look at other function formulas!
Do you think that it is possible to solve simple problems with cube roots without an online calculator, or even a pencil or paper? If you think that it is impossible, or that you are incapable of doing it check out this method, it is very easy.
However, it only works for perfect cubes. Forget all the rules in the arithmetic books and consider for a moment the following method described by Robert Kelly. First of all, it is essential to memorize the cubes of the numbers from 1 to 10 and the last digit of their cubes.
It is presented in the table below. When you have a number you want to find the cube root of look first at the thousands skip the last three digits. For example, for the number , , The thousands are The cube of 5 is and of 6 is Therefore it is obvious that the number you are searching for is between 50 and The next step is to ignore all the other figures except the last digit. We can see that it's 3, so check your memory or in our table. You will find that the number you are searching for is 7.
So the answer is 57! We remind you that this algorithm works only for perfect cubes! And the probability that a random number is a perfect cube is, alas, really low. You've got only a 0. If you're not sure about your number, just forget about that rule and use our cube root calculator Let's say you need to make a ball with a volume of To prepare it you need to know its radius.
As you probably know the equation for calculating the volume of a sphere is as follows:. So the equation for the radius looks like this:. You know that the volume is At first you need to switch to a different volume units. Now you can solve the radius:. With our root calculator you can also calculate other roots.
Just write the number in the Degree of the root field and you will receive any chosen nth root calculator. Our calculator will automatically do all necessary calculations and you can freely use it in your calculations! So, let's take some examples. Let's assume you need to calculate the fourth root of First you need to write the appropriate number you want to root - Than change the degree of the root to 4. And you've got the result!
The fourth root of is 6. Our nth root calculator also enables you to calculate the root of irrational numbers. It's value is constant for every circle and is approximately 3. First write in the number box. Than change the degree of the root - let's round and write 3. And now you can see the result. For example if you are finding the cube root of a number, n will be 3.
Press "multiply button and then equal to button" 12 times. Also remember that when you press multiply and the equal to sign together on the simple calculator , you are effectively trying to get the square root of square numbers i. Before doing anything, hit the following buttons to make sure your calculator is clear:. The 2nd button is at the top left of your calculator and the CLR Work button is located at the bottom left of your calculator.
