What is a cube root function?
The cube root function is the inverse of the cube function. So, given a number y, the cube root function seeks to find a number, x, such that multiplying 1 by that number 3 times gives y. [Note that this is equivalent to multiplying the number by itself two times, not three.] That is, cuberoot(y) = x <=> x^3 = y For example, 2*2*2 = 8 so the cube root of 8 is 2. 1.5^3 = 3.375 so the cube root of 3.375 is 1.5 (-3)^3 = -27 so the cube root of -27 is -3. The cube root of y is denoted by y^(1/3). It can also be written using the radical symbol like for a square-root, but the radical must be preceded by a superscript 3. Apologies, but this browser is crap and so I cannot show that representation.
If x and y are integers is x less than y if The cube of x is less than the cube of y?
Yes it is.
What is the cube root of y?
y^1/3
How do work out 216 feet in to square yards?
If a square box has a perimeter of 216, then you know that 4s=P P=216 216/4=s s=54 There's 3 feet per yard so 54/3=y y=18 182=324 yds2
What is the definitions for cubed root?
The cubed root of a number x gives a number y such that y^3 = x. The cube root can be represented by the power of 1/3. e.g. 8^(1/3) which is read 8 to the power one third or the cube root of 8 equals 2. Because 2X2X2=2^3 = 8 other examples 27^(1/3) = 3 64^(1/3) = 4 1000^(1/3) = 10

What do you meant by array of structures?
The elements of the arrays are structures. Example: struct { int x, y, z; } cube [8]; cube[0].x = 1;
If x and y are integers is x less than y if The cube of x is less than the cube of y?
Yes it is.
What is the cube root of y?
y^1/3
How come the function y cube root x2 - 1 has the domain -infinity infinity What is the procedure to coming to this solution?

How do you square a number and cubing a number?
For number = Y, the square is Y*Y, the cube is Y*Y*Y
What are the factors of y3-216?
(y - 6)(y2 + 6y + 36)
Is cube a quadrilateral?
No.
What is the y intercept of 2x-y equals 8?
-6
How do you factor y3-216?
For the problem, 3y-216, you need to look at what the common factors are in this problem. Since 216 doesn't contain a y, you only thing that may be factored out of both of these is a 3, since both 3y and -216 are divisible by 3. So, the answer would be: 3(y-72) You may check this is write by using distributive property to check your work.
