Summation of Powers Calculator
Calculate 1^k + 2^k + ... + n^k with formulas and see all calculation steps.
Formula Reference:
For small powers, you can use formulas:
- Sum of first n numbers: 1 + 2 + ... + n = n(n+1)/2
- Sum of squares: 1² + 2² + ... + n² = n(n+1)(2n+1)/6
- Sum of cubes: 1³ + 2³ + ... + n³ = (n(n+1)/2)²
