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.
What is the cubed root of x2y4?
y times the cube root of x2y
What is the cube root of y to the 15th power?
Using the symbol "^" for powers: (y^15)^(1/3) = y^(15 times 1/3) = y^5.
What is cube root of 4 times cube root of 12?
2 cube root 6
How is the square root of 16 related to the cube root of 16?
Suppose sqrt(16) = x and cuberoot(16) = y, then then x^2 = 16 = y^3 so that x^(2/3) = y x = y^(3/2).

What is the difference between a cube and a cube root?
The cube of a number is the value of the number multiplied by itself two times (or 1 multiplied by the number three times). A cube root is the inverse function so that if y is the cube of x the x is the cube root of y.
What is the cubed root of x2y4?
y times the cube root of x2y

How do you factor X to the third power plus Y to the third power?
x^3+y^3 Cube root of the first, x plus cube root of the last, y times What it takes to make the first number, x^2 Opposite sign, - Product of the two cube roots, -xy Then what it takes to make the last. (x+y)(X^2-xy+y^2)
What is the cubed root of x4y4?
You can divide each exponent by three; thus, you get: x4/3y4/3 This is equivalent to x (cubic root of x) y (cubic root of y).
What is the cube root of y to the 15th power?
Using the symbol "^" for powers: (y^15)^(1/3) = y^(15 times 1/3) = y^5.
What is cube root of 4 times cube root of 12?
2 cube root 6
How can you find the side of a cube using a cube root?
The cube root is the side of a cube.
What does it mean when there is a little number above the square root symbol?
It means it is a different kind of root, such as a cubic root, which has a three above the square root symbol ('radical sign'). If y is the square root of x, it means that y2 = x. So the square root of 4 is 2, and 22 is 4. If y is the cube root of x, it means that y3 = x. So the cube root of 8 is 2, and 23 = 8.
Is a cube root the same as multiplying a number by 3?
Not at all Cubic root of a number z is the number y such that y x y x y = y3 = z For example the cubic root of 64 is 4 because 4 x 4 x 4 = 43 = 64
