What does this symbol mean √?
√ is the symbol for square root. A square root is the number that, when multiplied by itself, gives the original number. For example, the square root of 4 is 2, because 2 x 2 = 4.
What is a cube root of 4?
(1.6+1.6+1.5625)/3 = 4.7625/3 = 1.5875. Therefore, we get the value of the cube root of 4 equal to 1.5875, which is an almost accurate number.
Is a cube root a function?
The domain of a cube root function is the set of all real numbers. Unlike a square root function which is limited to nonnegative numbers, a cube root can use all real numbers because it is possible for three negatives to equal a negative.
Does a cube root have two answers?
2 Answers. −2 isn’t a cube root of 8. If you’re sure your book’s claiming it is, then that’s a typo. You’re right that numbers only have one cube root, as long as we’re sticking to real numbers.
What does six cubed mean?
The cube of the number 6, or 6 cubed, is 216. To find the cube of a number, x, we raise the number x to the third power, or to the exponent 3.
Is 27 a cube number?
