The cube root of 81 is 4.
To find the cube root of 81, you can use a calculator or manually calculate it.
If you're using a calculator, you can directly input 81 and then calculate the cube root. The answer should be 4.3267487109222245.
If you want to calculate it manually, you can use the method of prime factorization. To find the cube root of 81, you need to find the prime factors of 81 and then divide the total exponent of each prime factor by 3.
The prime factorization of 81 is 3^4 because 3 * 3 * 3 * 3 equals 81.
Now, divide the exponent of 3 (which is 4) by 3. 4 divided by 3 is equal to 1 with a remainder of 1.
The result is 3^1 with a remainder of 1. This means that the cube root of 81 is equal to 3, with a remainder of 1.
So, the correct answer is 3.
