Cube Root of 192

In math, the cube root of a number like 192 is a number that, when multiplied by itself two times, is equal to 192.

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):

∛192

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, 192, is called the radicand.

To explain the cube root a little more, the cube root of the number 192 is a number (which we call n) that when multiplied by itself twice is equal to 192:

n × n × n = 192

∛192 is the same as 192 and so if you are solving a problem in a spreadsheet like Excel, Numbers, or Google Sheets, you can use =192^(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 192 and pressing the [∛x] button, to give the following answer:

∛192 ≈ 5.7689982812296

Is 192 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 192, we know that the cube root is 5.7689982812296, and since this is not a whole number, we also know that 192 is not a perfect cube.

Is the Cube Root of 192 a Rational or Irrational Number?

Another common question you might find when working with the roots of a number like 192 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 192 is not a rational number then, because we know it is not a perfect cube.

Rounding the Cube Root of 192

Sometimes when you work with the cube root of 192 you might need to round the answer down to a specific number of decimal places:

10th: ∛192 = 5.8

100th: ∛192 = 5.77

1000th: ∛192 = 5.769

Simplifying the Cube Root of 192

It is possible to simplify the cube root of 192 if the radicand can be made smaller. When that is possible, it is called the cube root of 192 in its simplest radical form.

In this example, the cube root of 192 in its simplest form is:

∛192 = 4∛1
