Adding numbers led to wanting to "undo" addition, and thus the definition of subtraction. Subtraction is needed to help solve problems that involve addition, and addition is needed to help solve problems that involve subtraction.
Multiplying numbers led to wanting to "undo" multiplication, and thus the definition of division. Division is needed to help solve problems that involve multiplication, and multiplication is needed to help solve problems that involve division.
Raising numbers to powers led to wanting to "undo" exponentiation, and thus the definition of roots. Roots are needed to help solve problems that contain a constant exponent, and exponents are needed to solve problems that involve a constant root.
Therefore, cube roots started as a way of solving problems that involved cubed quantities - such as volumes. A typical problem could be something like: if I wish to design a cube that will hold exactly 1,000 cubic inches of water, what must the length of each inside edge be? Since all three dimensions of a cube have the same length (L), this problem can be expressed mathematically by:
L^3 = 1,000
and the only way to solve for L mathematically is to "undo" the third power (cube) by taking the cube root of both sides:
L = 10
All numbers have cube roots (not necessarily integral cube roots) so every prime has cube roots.
Yes.
there is no cube roots in negative
you are my friend
The cube root of 0.064 is 0.4
Some calculators have a cube root function
4
The answer depends on "different from WHAT?" Positive cube roots, or negative square roots?
For school you will need to learn how to find square and cube roots in order to have the needed prerequisites to answer progressively harder and more complex problems.
an alg expression involving square roots, cube roots, etc
There are 3 cube roots and these are:the real root -1.2599and the complex roots 0.6300 - 1.0911i and its conjugate, 0.6300 + 1.0911i.
no, -6 is the cube root of -216.
