For reasons of hygiene and safety, personal grooming products, cosmetics or items of intimate clothing cannot be returned. A perfect cube results when you cube an integer, or a whole number without decimals or fractions. For example, 3 cubed is written as 3³ and 3³ = 3 × 3 × 3 = 27.

In the next section we elaborate on the cube 9. What is 9 Cubed? A cube is a three-dimensional shape with 6 equal square faces. Kaleidoscopes: Selected Writings of H.S.M. Coxeter, edited by F. Arthur Sherk, Peter McMullen, Anthony C. Thompson, Asia Ivic Weiss, Wiley-Interscience Publication, 1995, ISBN:978-0-471-01003-6 [1] Really, any number that is by itself, say 9, can be written as since we have just one 9. However, this is not really necessary as we can see this by just writing 9, so an indices of 1 is never really used. But you should know that any number with an indices of 1 does nothing to the number.

Unwanted Food or Drink Products - Once supply conditions are broken, there are a number of factors outside of our control that can affect the quality of a product. Therefore perishable goods such as food and drink cannot be returned. while the interior of the same consists of all points ( x 0, x 1, x 2, x 3, x 4, x 5, x 6, x 7, x 8) with −1< x i<1. Square Calculator uses this strict interpretation. Without parentheses -4² means "the negative of 4²" which is -16. So, all square roots have a positive OR negative answer and should always be written in the form as above. Cube numbers

However, from the last section we know that since a negative multiplied by a negative is equal to a positive. So there are two numbers, 4 and , which could have been multiplied by themselves to get to the number 16. Therefore, when we do the square root of a number, the answer can be either positive or negative. So, the answer to the square root of 16 is:As we have just seen, the use of indices tells us how many times a number is multiplied by itself, and when we have 3 as the indices, this is known as ‘cubing’ a number. The first five cube numbers are: Nine Cubed You now know everything about the cube 9 and calculating it by means of multiplication, exponentiation, sum and difference formulas and using identities: A sequence of numbers which you should become familiar with is the square numbers. These are the numbers that you get when squaring 1, 2, 3, 4…

It can be named by its Schläfli symbol {4,3 7}, being composed of three 8-cubes around each 7-face. It is also called an enneract, a portmanteau of tesseract (the 4-cube) and enne for nine (dimensions) in Greek. It can also be called a regular octadeca-9-tope or octadecayotton, as a nine-dimensional polytope constructed with 18 regular facets. The sum and the differences of two cubes, for example with side length 9 and 8, can be calculated with the following formulas: This 9-cube graph is an orthogonal projection. This orientation shows columns of vertices positioned a vertex-edge-vertex distance from one vertex on the left to one vertex on the right, and edges attaching adjacent columns of vertices. The number of vertices in each column represents rows in Pascal's triangle, being 1:9:36:84:126:126:84:36:9:1. When you cube a negative number the result will always be a negative number. But it is important to understand how using parentheses affects the intepretation of the operation.Coxeter, Regular Polytopes, (3rd edition, 1973), Dover edition, ISBN 0-486-61480-8, p.296, Table I (iii): Regular Polytopes, three regular polytopes in n-dimensions (n≥5) It may be helpful to use parentheses to clearly indicate which exponent calculation you intend. For example with even exponents and a negative sign the parentheses affect the result. Kaleidoscopes: Selected Writings of H.S.M. Coxeter, edited by F. Arthur Sherk, Peter McMullen, Anthony C. Thompson, Asia Ivic Weiss, Wiley-Interscience Publication, 1995, ISBN 978-0-471-01003-6 [1] You can see you'll always get a negative result with an odd exponent and a negative sign, whether it's inside or outside of parentheses. But when you have an even exponent the result depends on the interpretation of the negative sign and the presence of parentheses.

Putting a negative sign before the number or outside of parentheses means "take the negative of the number, cubed" as in

n³. You pronounce it as " n cubed," or " n to the third power." To get the cube of a number multiply it by itself 3 times.
