Question: What is the smallest prime number that can be expressed as the sum of four consecutive cubes starting from 2161?

To find the answer, we need to determine four consecutive cubes whose sum is equal to or greater than 2161. When we start with 12^3 = 1728, adding the next three consecutive cubes (13^3, 14^3, and 15^3), we obtain a sum of 4440. Thus, the smallest prime number that can be expressed as the sum of four consecutive cubes starting from 2161 is 4440.

Math question: What is the square root of (2161 multiplied by 2) minus the cube root of (2161 divided by 3) plus the fourth root of (2161 to the power of 4)?

The square root of 4322 minus the cube root of 720.33 plus the fourth root of 50209216808121 equals approximately 65.245.

Math question: What is the square root of the sum of the digits of the number 2161 divided by the difference between the number 2161 and the product of its digits?

The sum of the digits of 2161 is 2 + 1 + 6 + 1 = 10. The product of its digits is 2 * 1 * 6 * 1 = 12. The difference between 2161 and 12 is 2149. Now, taking the square root of 10 and dividing it by 2149, we get a result of approximately 0.006179.
