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.

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.

Let 'a' be the length of the side of the cube.

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.

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.
