Cube root of 648

Cube root is the operation of finding what number, when multiplied by itself three times, gives the output as Cube roots are seen across mathematics, as well as other disciplines like Physics and Chemistry, too. Find out what the cube root of is by looking at a detailed step-by-step solution. For example, when we say that we cubed the number 2, we are asking what the product is after multiplying 2 three times by itself : 2 x 2 x 2, which gives 8 so the cube of 2 is 8. However, when a question asks for a cube root, we ask ourselves: what number when multiplied by itself three times produces that number. To use the same example, if we want to find the cube root of 8, we see that we can multiply 2 x 2 x 2, and the cube root of 8 is 2. Two other ways we can represent the cube root of is:. If the number is small and perfect, you might be able to tell what the cube root is just by looking at the problem, but sometimes when the number is big, it is best to find the prime factorization of and rewrite as its prime factorization. Remember : Be prepared knowing that sometimes, the cube root of a number may not be perfect. A perfect cube root means that the answer is a whole number and not a decimal. However, if your cube root is not perfect, then you would have a decimal answer. Unfortunately, there is no way to get rid of the cube root so that must mean our answer is not a perfect cube root and the only way is to punch it in the calculator to get a decimal answer. Take advantage of our free downloadable resources and study materials for at-home learning. One thing we teach our students at Thinkster is that there are multiple ways to solve a math problem.

If the number is cube root of 648 and perfect, you might be able to tell what the cube root is just by looking at the problem, but sometimes when the number is big, it is best to find the prime factorization of and rewrite as its prime factorization.

In math, the cube root of a number like is a number that, when multiplied by itself two times, is equal to To explain the cube root a little more, the cube root of the number is a number which we call n that when multiplied by itself twice is equal to When the cube root of a given number is a whole number, this is called a perfect cube. Perfect cubes are important for many mathematical functions and are used in everything from carpentry through to more advanced topics like physics and astronomy. If we look at the number , we know that the cube root is 8. If you want to learn more about perfect cube numbers we have a list of perfect cubes which covers the first perfect cube numbers. Another common question you might find when working with the roots of a number like is whether the given number is rational or irrational.

In this article we will look at the cube root of the number and show you how to calculate it and determine if it is a perfect cube or not. The cube root of is another number that when multiplied by itself twice, would be exactly equal to We would normally express this problem in mathematical form by using the cube root symbol with the number alongside it:. You might notice that this symbol is very similar to the square root symbol. The only difference is the number, called the index, above the symbol, which lets us know this a cube root calculation. The basic formula we use to calculate a cube number from the result is a number which we'll call n in this example, that when multiplied by itself twice, is equal to

The cube root of a number answers the question "what number can I multiply by itself twice to get this number? Usually the radical spans over the entire equation for which the root is to be found. It is called a "cube" root since multiplying a number by itself twice is how one finds the volume of a cube.

So we write x 4 in front of the radical, and the base x to the remainder power, x 2 inside the radical: Then we have y It is possible to simplify the cube root of if the radicand can be made smaller.
