Question

cube and cube root definition​

Answer 1

Answer:

Cube:

To cube a number, just use it in a multiplication 3 times ...

Example: What is 3 Cubed?

3 Cubed=  =3 × 3 × 3= 27

Note: we write "3 Cubed" as 33

(the little 3 means the number appears three times in multiplying)

Cubes From 03 to 63

0 cubed=03=0 × 0 × 0=01 cubed=13=1 × 1 × 1=12 cubed=23=2 × 2 × 2=83 cubed=33=3 × 3 × 3=274 cubed=43=4 × 4 × 4=645 cubed=53=5 × 5 × 5=1256 cubed=63=6 × 6 × 6=216

Cube root:

The cube root of a number is a special value that, when used in a multiplication three times, gives that number.

Example: 3 × 3 × 3 = 27, so the cube root of 27 is 3

Answer 2

Answer:

The cube roots of a number x are the numbers y which satisfy the equation. y 3 = x i.e a number that multiplies by itself three times in order to create a cubic value. A perfect cube is a whole number which is the cube of another whole number.
