To find the cube root of 81, you can use the fact that x^3 = 81, and solve for x.

Step 1: Start with the number 81
Step 2: Take the cube root of 81, which is denoted as ∛81
Step 3: The cube root of 81 is 4, since 4 * 4 * 4 = 64, and 4 * 4 * 4 * 4 = 256.

Therefore, the cube root of 81 is 4.

To find the cube root of a number, you need to find the number that, when multiplied by itself twice, gives you the original number. To find the cube root of 81, you can start by taking the cube root of 81 using a calculator or by performing the calculation manually.

To do this manually, you can use the concept of prime factorization. Prime factorization breaks down a number into its prime factors. For example, 81 can be expressed as 3 x 3 x 3.

To find the cube root of 81, you can group the prime factors into sets of three:

(3 x 3 x 3) = 27 x 3 = 27 x √3

Therefore, the cube root of 81 is √3, which is approximately 2.828.
