You know to find out which out which number has been timed by itself to make the number in the square root. For example: If the number inside the square root is 49, you need to find out which number has been timed by itself to make 49. As you may know, the number inside the square root is always a square number, so I would advise you to learn the list of square numbers. 7 x 7= 49, so the square root of 49 is 7. Remember that Evaluate simply means work out. So when to asked to evaluate a square number, cube number, square root, cube root etc., simply just work it out. Evaluating powers and roots is grade D in maths.

10 grids, stacked, would make a thousand cube.

196's prime numbers are (2) (2) (7) (7). For example, if you square those prime numbers you would get 14. Why? Because u need equal integers within a square root, so that you can take that integer outside the square root. With the same knowledge, we can apply ask the question whether 196 is a cube root. If it's a cube root, then it needs to have 3 same integer (ex: 3x3x3x4x4x4x; 2x2x2x7x7x7). As you can see we don't have third same integer. Also, even if it is 2x2x2x7x7, it cannot be a cube root because it is missing the third 7. So the answer is that 196 is a perfect square and not a perfect cube. Note: you cannot have a square root of a negative integer, if the question is "is -196 a perfect square or a perfect cube", then the answer is neither. Of course you can SQUARE the negative number (ex: (-2)^2=+/- 4), but you cannot mathematically square root a negative number unless your using the imaginary integer "i". I hope it answers your question and just a bit more.

A vertex is defined in Geometry and the point at which two lines or segments connect. If we think of a 2D square first we can count that it in fact has 4 vertices. One at the top left, one at the top right, one at the bottom left, and one at the bottom right. We understand in Geometry that a 3D object is a 2D object with an additional plane of space. So knowing this we can assume that there would have to be an additional 4 vertices to formulate a 3 Dimensional square - which is now a cube. So in conclusion If a 2D object has 4 vertices, then a 3D object since it has an additional plane of space would need an additional 4 vertices to make a square on the second plane of space. So we need a total of 8 vertices to make a 3D cube (3D square - though in technicality a square is 2D, a cube is 3D)

Yes, sometimes you need to do that.

Because it's a faster way of grouping numbers together.

In surd form, square roots need to be have the same radical term before you can add or subtract them. However, unlike in algebraic expressions, it is possible to add or subtract square roots using approximate (decimal) values.

Use a calculator (if you need) to find the principal square root. The second square root is the negative of the number.

First, by sides, you mean faces. Second, by square prism, you mean cube. That said, a cube has 6 faces, 8 vertices, and 12 edges. * * * * * No, second. By square prism you do not need to mean cube. A cuboid : AxAxB is a prism of length B and a square cross-section of AxA units.

You need to know how to 'cube ' a number , to calculate Volumes of things. You also need to know how to calculate a 'cubed root' to find the lengths of the sides of a box which is cube shaped . Engineers use special formulas which involve cube and cube root. Most people have no need in their life, to perform these mathematical processes, but school students are taught these processes, so that they will learn how to think and how to develop their brain, and how to solve problems in life.

You would need 12 straws of equal sizes because a cube has 12 equal edges, 8 vertices and 6 faces

It so happens that squares and square roots (as well as other powers and roots) frequently occur in different scientific problems - physics, for example. An engineer must know such things. (Engineerings is basically "applied science".) If you are not planning to work in an engineering field, you'll probably not use much square roots, or other advanced math.
