Math Problem Statement

CALCULATE TYHE SUM OF K TIMES 2 POW K FROM K=0 TO H

Solution

The problem is to compute the sum of the series:

S=k=0hk2kS = \sum_{k=0}^{h} k \cdot 2^k

To solve this, we use the following approach:


Step 1: Derive the formula for the series

The summation involves k2kk \cdot 2^k, and its exact summation formula can be derived using algebraic manipulation and calculus. The result for the sum is:

S=(h1)2h+1+2S = (h - 1) \cdot 2^{h+1} + 2

This formula is valid for h1h \geq 1. If h=0h = 0, the sum is simply 020=00 \cdot 2^0 = 0.


Step 2: Compute for given hh

Substitute the desired value of hh to calculate SS. Let me know if you'd like to calculate for a specific value of hh, or you can specify further constraints or changes to the series.

Would you like me to show the derivation of the formula, verify it with an example, or calculate for a specific hh?


Here are related questions to expand on this:

  1. How is the formula for this summation derived?
  2. Can we compute the same sum using programming or computational tools?
  3. What happens if the limits change (e.g., k=1k = 1 to hh)?
  4. How is this related to geometric or arithmetic series?
  5. Are there alternative methods to derive this summation?

Tip: Understanding series summations often requires a combination of basic algebra, calculus, and pattern recognition.
