In math, the cube root of a number like 1033 is a number that, when multiplied by itself two times, is equal to 1033.
We would show this in mathematical form with the cube root symbol, which is similar to the radical symbol (√) used in a square root, but which also has the number 3 above the symbol (this number is called the index):
So, the √ is called the radical symbol, the little 3 above it is the index (which means multiply by itself two more times), and the number, 1033, is called the radicand.
To explain the cube root a little more, the cube root of the number 1033 is a number (which we call n) that when multiplied by itself twice is equal to 1033:
∛1033 is the same as 1033⅓ and so if you are solving a problem in a spreadsheet like Excel, Numbers, or Google Sheets, you can use
=1033^(1/3) to calculate the cube root.
For the purposes of this article, we'll use a scientific calculator to work out the cubic root by typing the number 1033 and pressing the
[∛x] button, to give the following answer:
Is 1033 a Perfect Cube?
When the cube root of a given number is a whole number, this is called a perfect cube. Perfect cubes are important for many mathematical functions and are used in everything from carpentry through to more advanced topics like physics and astronomy.
If we look at the number 1033, we know that the cube root is 10.108811706815, and since this is not a whole number, we also know that 1033 is not a perfect cube.
If you want to learn more about perfect cube numbers we have a list of perfect cubes which covers the first 500 perfect cube numbers.
Is the Cube Root of 1033 a Rational or Irrational Number?
Another common question you might find when working with the roots of a number like 1033 is whether the given number is rational or irrational. Rational numbers can be written as a fraction and irrational numbers can't.
The quickest way to check if a number is rational or irrational is to determine if it is a perfect cube. If it is, then it's a rational number, but if it is not a perfect cube then it is an irrational number.
We already know that 1033 is not a rational number then, because we know it is not a perfect cube.
Rounding the Cube Root of 1033
Sometimes when you work with the cube root of 1033 you might need to round the answer down to a specific number of decimal places:
10th: ∛1033 = 10.1
100th: ∛1033 = 10.11
1000th: ∛1033 = 10.109
Simplifying the Cube Root of 1033
It is possible to simplify the cube root of 1033 if the radicand can be made smaller. When that is possible, it is called the cube root of 1033 in its simplest radical form.
In this example, the cube root of 1033 cannot be simplified down any further.
