Math Problem Statement
Solution
The problem asks us to divide 24 into three parts, such that the continued product of the first, the square of the second, and the cube of the third is maximized. Let us solve this step by step:
Step 1: Let the three parts be , , and , such that:
The quantity to maximize is:
Step 2: Express in terms of and :
From , we get:
Substitute this into the expression for :
Step 3: Use optimization techniques:
To maximize , we need to find the critical points by taking partial derivatives of with respect to and and setting them equal to zero.
This is a complex calculation, so let us proceed numerically and/or analytically to find the optimal values.
Step 4: Use symmetry and the AM-GM inequality:
For maximum product values, the numbers are typically distributed in a ratio that balances their growth factors. Using optimization principles or numerical computation, the best partition comes out to be:
Step 5: Verify:
For , , , the value of the product is:
Simplify:
This is the maximum value of .
Final Answer:
The three parts are:
