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.

Cube root of 648

The square root of rounded up to 5 decimal places is The square root of , or root , is the number which when multiplied by itself gives the product as Therefore, the square root of by long division method is Hence, the square root of is an irrational number. Find the radius of the circle. Let 'r' be the radius of the circle. Example 3: If the surface area of a cube is in 2. Find the length of the side of the cube. Let 'a' be the length of the side of the cube. The square root of is Upon prime factorizing i.

Square Root of Solved Examples. In math, the cube root of a number like is a number that, when multiplied by itself two times, is equal to

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:.

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 This means you can use that formula in Excel, Google Sheets, or Mac Numbers to calculate the cube root:. We calculated the cubic root of for this article using a scientific calculator. If you have one yourself, you can confirm the results by typing the following into the calculator:. Whenever the cube root of a given number is a whole number without any fractional or decimal part, we call this a perfect cube.

Cube root of 648

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. Unlike the square root, there is only one unique real number root as a result from applying the cube root function for a given number and it carries the sign of the number. The real number cube root is the Principal cube root, but each real number cube root zero excluded also has a pair of complex conjugate roots. Our cube root calculator will only output the principal root.
