Cube Root 1 to 20
Cube Root 1 to 20 is the list of cube roots of all the numbers from 1 to 20. Cube roots can be determined for both negative and positive numbers. The values of cube roots from 1 to 20 range from 1 to 2.71441.
In cube roots from 1 to 20, the numbers 1 and 8 are perfect cubes and the remaining numbers are non-perfect cubes i.e. their cube root will be irrational. The cube root 1 to 20 in radical form is expressed as ∛x and in the exponential form, it is expressed as (x)⅓.
Cube Roots 1 to 20:
- In radical form: ∛x
- In exponential form: (x)⅓
Where x is any number between 1 to 20.

FAQs on Cube Root 1 to 20
What is the Value of Cube Root 1 to 20?
The value of cube root 1 to 20 is a number (x⅓) when multiplied three times gives the original number. It can have both negative and positive values. Between 1 to 20, the cube roots of 1 and 8 are whole numbers (rational), while the cube roots of 2, 3, 4, 5, 6, 7, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20 are decimal numbers that are neither terminating nor recurring (irrational).
What Values of Cube Roots from 1 to 20 are Between 2.5 and 3 inclusive?
The values of cube roots 1 to 20 between 2.5 and 3 are ∛16 (2.520), ∛17 (2.571), ∛18 (2.621), ∛19 (2.668), and ∛20 (2.714).
What are the Methods to Calculate Cube Roots from 1 to 20?
There are two methods commonly used to calculate the value of cube roots from 1 to 20. For perfect cubes (1, and 8), we can use prime factorization method and for non-perfect cubes (2, 3, 4, 5, 6, 7, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20) long division method can be used.
What is the Value of 3 Plus 2 Cube Root 3?
The value of ∛3 is 1.442. So, 3 + 2 × ∛3 = 3 + 2 × 1.442 = 5.884. Hence, the value of 3 plus 2 cube root 3 is 5.884.
How Many Numbers in Cube Roots 1 to 20 are Rational?
The numbers 1, and 8 are perfect cubes so their cube roots will be whole numbers i.e. can be expressed in the form of p/q where q ≠ 0. Hence, the cube roots of 1 and 8 are rational numbers.
If you Take Cube Root from 1 to 20, how many of them will be Irrational?
The numbers 2, 3, 4, 5, 6, 7, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20 are non-perfect cubes. Hence their cube root will be an irrational number (cannot be expressed in the form of p/q where q ≠ 0).
